Which of the choices below is an equation?

• 7

• -2x

• 9+x=13

• 2x+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.
