Solving One-Step Equations

In the equation

x + 7 = 12

Describe the steps you should take to solve for x.

• 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 = 5.

What should your first step be in solving for k?

• Divide both sides by 11. The solution is 176.

• Multiply both sides by 11. The solution is 176.

• Add 11 to both sides. The solution is 27.

• Subtract 11 to both sides. The solution is -11.

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

Solve the equation

3x = 27

• x = 24

• x = 81

• x = 9
