Question

Select the action you would use to solve 3x = 12. Then select the property

that justifies that action.
Select all that apply.
O A. Action: Add 3 to both sides.
B. Action: Multiply both sides by 3.
O C. Action: Divide both sides by 3.
D. Property: Addition property of equality
O E. Property: Multiplication property of equality
F. Property: Division property of equality

Answer 1

C. Action: Divide both sides by 3.

F. Property: Division property of equality

Explanation:

you are trying to get x by itself so if you divide by 3 you are taking the 3 from x, and what you do to one side you do to the other.

Answer 2

C. Action: Divide both sides by 3.

F. Property: Division property of equality.

Explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

First, divide 3 from both sides of the equation:

(3x)/3 = (12)/3

x = 12/3

x = 4

C. Action: Divide both sides by 3.

F. Property: Division property of equality.
