How do you solve y−3x=13 for y in the easiest possible way?

Answer 1

Simply add 3x to both sides:

y - 3x + 3x = 13 + 3x

y = 3x + 13

Answer 2

When it says solve for y it just means get y by itself on one side. The easiest way to achieve this is by getting rid of the 3x. Since the 3x is being subtracted from y, we must do the opposite (add 3x) to both sides:

y - 3x = 13

+3x +3x

y = 3x + 13
