using substitution solve y=5x-7 and show the steps but simple please because its hard for me to understand

Answer 1

unless there's more information, the only thing left to solve for is x, as it's already solved for y.

y=5x-7

add 7 to both sides

y+7 = 5x -7 + 7 = 5x+0 = 5x

y+7 = 5x

divide both sides by 5 to get

(y+7)/5 = 5x/5 = x

x = (y+7)/5
