Solving Multi-Step Equations (with Distributive Property)

Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac. It allows you to multiply a single term by two or more terms inside a set of parentheses.

How do you isolate the variable in the equation (2x - 3) / 4 = 9?

Back

Multiply both sides by 4 to eliminate the fraction: 2x - 3 = 36, then add 3 and divide by 2 to find x = 19.5.
