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

Back

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

Front

Solve for a: 9a - 11 = 61

Back

a = 8

Front

Solve for b: 5b - 7 = 93

Back

b = 20

Front

Solve for x: 6x + 25 = 73

Back

x = 8

Front

Solve for d: 5d + 6 = 71

Back

d = 13

Front

Solve for n: 2n + 6 = 16

Back

n = 5

Front

What is the first step to solve the equation 3x + 4 = 10?

Back

Subtract 4 from both sides to get 3x = 6.

Front

What is the second step to solve the equation 3x = 6?

Back

Divide both sides by 3 to get x = 2.

Front

What does it mean to perform inverse operations?

Back

Inverse operations are operations that undo each other, such as addition and subtraction or multiplication and division.
