What is a simple algebraic equation?
An algebraic equation can be defined as a mathematical statement in which two expressions are set equal to each other. The algebraic equation usually consists of a variable, coefficients and constants. Also Check: Algebraic Expressions. In simple words, equations mean equality i.e. the equal sign.
Which is an example of an algebraic expression?
Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.
How to solve equations?
Here are some things we can do: Add or Subtract the same value from both sides. Clear out any fractions by Multiplying every term by the bottom parts. Divide every term by the same nonzero value.
What does an equation mean?
An equation says that two things are equal. It will have an equals sign "=" like this:
What is a Solution?
A Solution is a value we can put in place of a variable (such as x) that makes the equation true.
What is it called when we gather all solutions together?
When we gather all solutions together it is called a Solution Set
Is x=5 a solution?
For x=5 we get "5−2=4" which is not true, so x=5 is not a solution.
Can you apply a function to both sides?
Sometimes we can apply a function to both sides (e.g. square both sides)
Why do we have letters in algebra?
Explanation: In algebra you have letters to indicate the existence of an unknown value. These letters may be combined in various configurations with known values. You have two main groups of configuration. 1: Expression.
How to obtain a solution?
To obtain a solution we move things round in a way that is mathematically correct until we have just one of what we wish to find the value of on one side of the equals and everything else on the other.
What does the equal sign mean?
equals sign. This is just a statement and is not what is termed. solvable. 2.Equation. This has an equal sign that literally means the intrinsic. value of everything on one side of the equals is 'EXACTLY' the. same intrinsic value as on the other side.
How to have x on its own?
To have x on its own we need to remove the 6. The problem is that all on the left must be equal in value to all on the right. So if we remove 6 from the right we must also remove it from the left. Remove is 'subtract' so we have: Subtract 6 from both sides giving:
Is there a large number of correct mathematical manipulations?
There are a large number of correct mathematical manipulations. Knowing them is down to experience.
What does it mean to solve an algebraic equation?
Solving an algebraic equation just means manipulating the equation so that the variable is by itself on one side of the equation and everything else is on the other side of the equation . Once everything else is simplified, the equation is solved.
What is algebraic equation?
Algebraic equations are mathematical statements containing two expressions with equal value. Learn how to solve algebraic equations by exploring their definition and examples, including single variable equations. Understand that algebra is math with letters, and learn more by reviewing basic terminology and doing practice problems. Updated: 11/25/2021
Why does math say the same thing?
This is because mathematics was designed to express concepts and calculations in a much more concise fashion than other human languages.
Does moving except the variable to the other side of the equation work?
The same process we saw earlier (moving except the variable to the other side of the equation) works regardless of which operation is needed.
Is x a variable?
But, even after you know that, the x is still called a variable. The 3 in 3 x + 2 = 17 is called the coefficient, while the 2 and 17 are called constants; we can refer to them as constant terms.
Is algebra a letter?
Math with letters is really just an extension of math without letters. Algebra simply makes it easier to talk about something with an unknown value and not have to make a crazy statement like we just did. Mathematicians have agreed to call the letter that is used to represent an unknown quantity a variable.
Expert Answer
1) Expression. This is a collection of numbers and letters without an equals sign. This is just a statement and you can't solve it

How many solutions are there in a graph?
There is only one solution. In terms of graphs, this means there is only one x-intercept.
Is x = 0 a solution?
So, x = 0 is not a solution.
Can factoring solve an equation?
In some cases the equation can be solved by factoring, but the factorization is not obvious.
What Is An equation?
- An equation says that two things are equal. It will have an equals sign "=" like this: That equations says: what is on the left (x − 2) is equal to what is on the right (4) So an equation is like a statement "this equals that"
More Than One Solution
- There can be more than onesolution. When we gather all solutions together it is called a Solution Set
