Multi-step Equations

Solve: 10x + 9 = 4x - 9

• 3

• 0

• -18

• -3

Solve the equation: 4x - 5x + 9 = 5x - 9

• x=3

• x=-3

• x=-9

• x=9

In order to solve an equation, we must get variables on one side of an equation, and constants on the opposite side.

• False

• True

Solve: 10x + 9 = 4x - 9

• x=3

• x=0

• x=-3

• x=18

Solve: 2(4x-3) - 8 = 4 + 2x

• x=5/3

• x=3

• x=1

• x=2

Solve: 14p - 8 = 22 + 20p

• -5

• 5

• 30

What is the first step to solving this equation:

-11 - 3x = 44 - 2x

• Add 11 to both sides

• Get the variable on one side

• Add 3 to both sides

• Add 2 on both sides.

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

• Find the coefficient

• Find the value of the variable

• Find the constant

• Be confused

Solve the following equation for x:

5x − 6 = 8 − 2x

• x = 2

• x= −2

What is the first step you should take to solve this problem?

1 + 4n - 6n = 1 - 8n

• subtract 8n to both sides

• multiply 6n to both sides

• combine the like terms 4n + -6n
