Solve One Step Equation Given A Variable

Solve for x.

x + 12 = 20

• x = 8

• x = -32

• x = 32

• x = -8

Evaluate (solve).

y - 4.6 = 12

• y = 16.6

• y = 5.8

• y = 7.4

• Answer not Given

Solve for x.

x - 8 = -5

• x = 13

• x = -13

• x = 3

• x = -3

When you solve one-step equations, you can do anything you want to one side of the equal sign, as long as...

• it is mathematical

• you do the SAME thing to the other side

• solving equations is impossible

Solve...
3x - 7 = 32

• 13

• -13

• 12

• -12

Solve...
2x - 3 = 1 

• 3

• 2

• 1

• -2

x-10=12

Solve for x.

Make sure to check your work. If you need to use scratch paper go ahead!

• x=26

• x=21

• x=34

• x=22

Solve the following equation.
