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. It typically involves addition or subtraction followed by multiplication or division.

Front

How do you isolate a variable in an equation?

Back

To isolate a variable, perform inverse operations to both sides of the equation until the variable is alone on one side.

Front

Solve for x: -3x + 5 = -13

Back

x = -6

Front

Solve for x: \frac{x-3}{4} = 10

Back

x = 43

Front

Solve for a: 6 - 3a = 21

Back

a = -5

Front

Solve for x: -4x + 1 = 21

Back

x = -5

Front

Solve for v: 8 = 4v + 12

Back

v = -1

Front

What is the first step to solve the equation 2x + 3 = 11?

Back

Subtract 3 from both sides to isolate the term with x.

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.

Front

If you have the equation 5x - 2 = 3, what is the first step to solve for x?

Back

Add 2 to both sides to start isolating x.
