Answer 2

1- start with the original equation

x=2y+70

Let y =3x

x=2x 3x+70

simplify

x=6x+70

2-solve for x.

x=6x+70

Subtract 6x from both sides

x-6x=70

simplify x-6x to -5x

-5x=70

divide both sides by -5

x=- 70/5

simplify 70/5 to 14

x=-14

3- start with an original equation .

y=3x

Let x =-14

y=3x -14

simplify

y=-42

therefore

x=-14

y=-42
