Which equation is equivalent to - 3x + y = 5?

A. Y = 5 + 3 = 3x

B. Y = 5 - 3x

C. Y = - 3x - 5

D. Y = 3x - 5

If, in an equation, we add or subtract something from both the left and the right side of an equation, the expression will still be correct. For example, if we have 5=5, and subtract 3 from both sides, we get 2=2, which is still correct. If we have x + 7 = x + 7, and we subtract 2, we get x + 5 = x + 5.

With that said:

-3x + y = 5 / if we're solving for y, add 3x to each side to isolate the y on the left side

y = 5 + 3x, and that should be your answer
