Solving Two-Step Equations with Inverses

This tutorial teaches how to solve equations using two inverse steps. It begins with identifying the variable and determining which side of the equation to work with. The tutorial explains how to clear fractions by multiplying by the denominator and using inverse operations to eliminate constants and coefficients. Several examples are provided to illustrate these steps, including handling fractions and coefficients in different positions. The lesson concludes with a summary of the techniques covered.

What is the first step in solving equations using two inverse steps?

• Identify the variable

• Use a calculator

• Clear the constants

• Multiply by the denominator
