First you have to replace x with 3y. the equation would be y=3y+5 so then u subtract 3y on both sides. you would get -2y. then divide -2 by 5. u would get y=-0.4.

You know that x=3, so you plug in 3 for x for the equation of y=x+5

After being plugged in, the equation for y will look like: y=3+5

You add and get y=8.
