Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

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

Back

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

Front

Solve for x: 3x + 9 = 24

Back

x = 5

Front

Solve for p: 12 - 3p = -12

Back

p = 8

Front

Solve for x: 2x - 4 = 8

Back

x = 6

Front

Solve for x: 5x + 10 = 35

Back

x = 5

Front

Solve for x: x/2 + 3 = 7

Back

x = 8

Front

Solve for x: 4x - 16 = 0

Back

x = 4

Front

What is the first step to solve the equation 2x + 6 = 14?

Back

Subtract 6 from both sides to get 2x = 8.

Front

What is the second step to solve the equation 2x = 8?

Back

Divide both sides by 2 to get x = 4.
