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:
4p = 16

• p = 12

• p = -12

• p = -4

• p = 4

y + 9 = -10

• 1

• -1

• 19

• -19
