Question

In the equation 3y = 21, what is the next step in the equation solving sequence

Answer 1

You divide 3 from 21 and y=7

Answer 2

divide both sides by 3

Explanation:

Solving the equation means to have y alone on the left side equaling a number.

Since the variable y is being multiplied by 3, the next step is to do the opposite operation to "multiplying by 3" which is "dividing by 3." Since the rule in algebra is that you must do the same operation to both sides of an equation, the next step is:

divide both sides by 3
