How do you isolate a variable in a two-step equation?

Back

To isolate a variable, perform the inverse operations in reverse order: first eliminate any addition or subtraction, then eliminate any multiplication or division.

Front

Solve the equation: 2x + 3 = 11

Back

x = 4

Front

Solve the equation: 5x - 7 = 18

Back

x = 5

Front

What is the first step to solve the equation: 3x - 4 = 11?

Back

Add 4 to both sides to isolate the term with x.
