Solve the following equation

X + 8 = 15

• 23

• -7

• 7

• -23

Solve the following equation

1 + a = 15

• 14

• 16

• 12

• - 16

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

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.

6x + 3(-x + 11) = 3

• -10

• 10

• 15

• -15
