Multiple Choice

In the equation

x + 7 = 12

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.

• Divide both sides by 7. The solution is x = 1.71

Multiple Choice
