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 are applied.

Front

Solve for x: 2x + 16 = 130

Back

x = 57

Front

Solve for r: 8r - 14 = 42

Back

r = 7

Front

Solve for x: 4x + 7 = 23

Back

x = 4

Front

Solve for p: 6p - 5 = 13

Back

p = 3

Front

Solve for x: 9 + 3x = 10

Back

x = 1/3

Front

What is the first step to solve the equation 2x + 16 = 130?

Back

Subtract 16 from both sides to get 2x = 114.

Front

What is the second step to solve the equation 8r - 14 = 42?

Back

Add 14 to both sides to get 8r = 56.

Front

What does it mean to perform the inverse operation?

Back

An inverse operation reverses the effect of the original operation, such as addition and subtraction or multiplication and division.
