Front

What is a 2-step equation?

Back

A 2-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

How do you isolate a variable in a 2-step equation?

Back

To isolate a variable, perform the inverse operations in the reverse order of operations.

Front

Solve for x: 12 = 5x + 17

Back

x = -1

Front

Solve for x: -1x + 10 = 5

Back

x = 5

Front

Solve for x: -3x + 8 = -1

Back

x = 3

Front

Solve for x: 3x - 7 = -16

Back

x = -3

Front

Solve for x: 4x - 5 = 11

Back

x = 4

Front

What is the first step to solve the equation 5x + 17 = 12?

Back

Subtract 17 from both sides to isolate the term with x.

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).

Front

What is the solution to the equation 2x + 3 = 11?

Back
