Front

Solve: 5x + 15 = 10x - 40

Back

x = 11

Front

Solve: 10 + 2n = 8n - 2n + 10

Back

Front

The goal of solving a one, two, or multi-step equations is to:

Back

Find the value of the variable

Front

3x = 15. What is the next step to solving this equation?

Back

divide 3

Front

What is a multi-step equation?

Back

An equation that requires more than one step to solve.

Front

What does it mean to isolate a variable?

Back

To get the variable alone on one side of the equation.

Front

What is the first step in solving the equation 4x + 8 = 24?

Back

Subtract 8 from both sides.

Front

What is the principle of balancing equations?

Back

Whatever you do to one side of the equation, you must do to the other side.

Front

What is a coefficient in an equation?

Back

A number that multiplies a variable.
