2 Step Equations

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 the reverse order of how they appear in the equation.

Front

Solve for y: 7y + 7 = -28

Back

y = -5

Front

Solve for x: 5x + 3 = -12

Back

x = -3

Front

Solve for y: -3y + 5 = 35

Back

y = -10

Front

Solve for y: -24 = -2y - 6

Back

y = 9

Front

Solve for y: -3y + 5 = 32

Back

y = -9

Front

What is the first step to solve the equation 2x + 4 = 12?

Back

Subtract 4 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.

Front

What does it mean to perform the inverse operation?

Back

An inverse operation reverses the effect of the original operation (e.g., addition and subtraction are inverses).
