5. Divide by the same number on both sides.

What is a 2 step inequality?

Two Step Inequalities are inequalities that take two steps to solve. This means that you have to add, subtract, multiply, or divide two times in order to solve the inequality. When solving each Two Step Inequality you will have to either add or subtract first and then multiply or divide second to solve the inequality.

What is a 2 step equation example?

Two step equations are algebraic equations and are the equations that can be solved in exactly two steps and gives the final value of the variable in two steps. Generally, two step equations are of the form ax + b = c, where a, b, c are real numbers. A few examples of two step equations are: 2x + 3 = 7.
