Answer:
B and E
Explanation:
Our equation right now is x/3 = 12, or x ÷ 3 = 12. In order to solve for x, we need to isolate it, which means getting rid of the 3. To do so, we must "counteract" the division with the opposite of division - multiplication.
We need to multiply (x/3) by 3 to get x. However, we can't just do that for the left side; by the Multiplication Property of Equality, we must multiply 3 to both sides in order to maintain the truth of the statement.
Thus, the answer is B (multiply both sides by 3) and E (multiplication property of equality).
