Solving One Step Equations

Solve the equation:

4p = 16

• p = 12

• p = -12

• p = -4

• p = 4

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

17 = x + 3

• x = 20

• x = 14

• x = 13

• x = 19

r - 18 = 27

• -45

• 45

• -9

• 9

Which equation has w = 8 as the solution?

• 8w= 64

• 16w = 240

• 16 - w = 9

• 4 + w = 10

In the equation

x + 7 = 12

7 is being added to the variable, x. How should you show your work to isolate the variable and solve the equation?

• Subtract 7 from both sides. The solution is x = 5.

• Add 7 to both sides.

  The solution is x = 19.

• Multiply both sides by 7 The solution is x = 84.

Solve the equation:

20.5 = x + 4

• 16.5

• 16.05

• 24.5

• 24.05

Solve the equation:

x + 7 = 12

• x = 5

• x = 19

• x = -5

• x = 84

Solve the equation:

x - 4 = -3

• x = -7

• x = 1

• x = 12

• x = -12

Solve the equation:

-5x = 25

• x = 20

• x = -20
