One and Two Step Equations

17 = x + 3

• x = 20

• x = 14

• x = 13

• x = 19

x + 12 = 20

• x = 32

• x = -32

• x = 8

• x = -8

x - 32 = 49

• x = 17

• x = 71

• x = 81

• x = 49

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.

5.    6b = 30

• x = 36

• x = 24

• x = 180

• x = 5

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

Choose the correct equation for the situation.
Jane is 3 years older than Sam. If Jane 12, how old is Sam?

• j - 3 = 12

• s - 3 = 12

• s + 3 = 12

• j + 12 = 3

Solve the equation:
-3 + x = -12

• x = 9 

• x = -15

• x = -9

• x = 15
