In the equation

x + 7 = -3

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 = -10.

• Add 7 to both sides.

  The solution is x = 4.

• Multiply both sides by 7 The solution is x = -21.

• Subtract 7 from both sides. The solution is x = 4.
