What are the four steps for solving an equation?
The four steps for solving an equation include the combination of like terms, the isolation of terms containing variables, the isolation of the variable and the substitution of the answer into the original equation to check the answer. The combination of like terms can also be referred to as simplifying. While this is not necessary as a first step, it is much easier to solve an equation when the terms are as simple as possible.
How do you solve equations step by step?
How do I solve algebra? Solve a two step equation by multiplying at the end instead of dividing. The principle for solving this type of equation is the same: use arithmetic to combine the constants, isolate the variable term, and then isolate the variable without the term. Let’s say you’re working with the equation x/5 + 7 = -3.

Step 1: Simplify Each Side of the Equation
As we learned last time, the first step in solving an equation is to make the equation as simple as possible. This means that you need to start by using the golden rule of equation solving and the order of operations, PEMDAS, to make the expression on each side of the equals sign as simple as possible.
Step 2: Move Variable to One Side
The next step in solving an equation for a particular variable is to use addition and/or subtraction to move every part of the equation that contains the variable you’re solving for to one side of the equals sign.
