one step equations

Solve the equation:
20.5 = x + 4

• 16.5
• 16.05
• 24.5
• 24.05

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.

The variable, k, is being divided by 11. How should you show your work to isolate the variable?

• Divide both sides by 11
• Multiply both sides by 11.
• Add 11 to both sides.
• Subtract 11 to both sides.
