Q. 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.
The solution is x = 19.
Multiply both sides by 7 The solution is x = 84.
• Question 2
180 seconds Q. The variable, k, is being divided by 11. How should you show your work to isolate the variable?
Divide both sides by 11
