How do you do two step inequalities with fractions?
- Step 1: Solve the inequality for y.
- Step 2: Graph the boundary line for the inequality.
- Step 3: Shade the region that satisfies the inequality.
- Step 4: Solve the second inequality for y.
- Step 5: Graph the boundary line for the second inequality.
- Step 6: Shade the region that satisfies the second inequality.
How do you solve inequalities with fractions?
Remember, with inequalities, if you multiply by a negative, flip the direction of the sign. When dealing with fractions, sometimes it is easier to deal with the fractions first and then move on to the problem. Do this by multiplying each term by the LCM (lowest common multiple) of the terms.
What is the first step in solving an inequality?
The first step in solving an inequality is to add the inverse of the constant. Remember to add it to both sides! Adding the inverse is just doing the opposite of what you see. Examples of inverses: '10 and -10' and '-5 and 5'.
How do you find the inequality of a sentence?
In an inequality, the two sides of the sentence are separated by an inequality sign, which indicates which side is larger through reference to the first side (> greater than or < less than). For example, 11 < 1/2x + 1 indicates that 11 is less than the value of 1/2x + 1.
How do you add an equal sign to an inequality?
Add an equal sign to the inequality symbol or just a line under it to indicate that the sides may be equal (11 <= x is read 11 is less than or equal to x). Inequalities that include an equal component work in exactly the same way as pure inequalities.
How do you solve inequalities with fractions step by step?
To solve an inequality use the following steps:Step 1 Eliminate fractions by multiplying all terms by the least common denominator of all fractions.Step 2 Simplify by combining like terms on each side of the inequality.Step 3 Add or subtract quantities to obtain the unknown on one side and the numbers on the other.More items...

What's an inequality fraction?
Roughly speaking, inequalities with fractions are inequalities with one or more fractions in which the unknown variable (e.g. ) occurs in the denominator or in both the numerator and denominator. First study the topic Equations with fractions before continuing this topic about inequalities.

What is the specification of a two step inequality?
The specification of a two-step inequality means exactly what it sounds like; it takes two steps to solve the inequality. We can, again, use our knowledge of a two-step equation to help us here. In a two-step equation, we needed to do two things in order to isolate the variable.
How to solve an inequality?
The first step in solving an inequality is to add the inverse of the constant. Remember to add it to both sides! Adding the inverse is just doing the opposite of what you see. Examples of inverses: '10 and -10' and '-5 and 5'. This requirement doesn't change if there is a fractional constant in the inequality; you still add the inverse of the fraction to both sides (removing it from the side without changing the ratio between the sides).
How does inequality work?
Think of a balance scale; an equation would have each side of the scale perfectly balanced, whereas an inequality results in one side of the scale being higher than the other. In an equation, the sides are separated by an equal sign (=). In an inequality, the two sides of the sentence are separated by an inequality sign, ...
