Answer:

x=12

y=6

Step-by-step explanation:

Let's first start by moving x and y to one side (I prefer having both variables on the same side and the other number on the other side):

3x-y=30

-3x+7y=6

Add the equations to eliminate x

6y=36

Divide both sides by 6

y=6

3x-30=6

Add 30 to both sides

3x=36

Divide both sides by 3

x=12

(x,y)=(12,6)
