Answer:

x = -3, y=2

Step-by-step explanation:

x+3y =3

3y -2x =12

Solve the first equation for x

x = 3-3y

Substitute this into the second equation

3y -2(3-3y) =12

Distribute

3y -6 +6y =12

Combine like terms

9y -6 =12

Add 6 to each side

9y-6+6 =12+6

9y =18

Divide each side by 9

9y/9 =18/9

y = 2

Now find x

x = 3 -3y

x = 3-3(2)

x = 3-6

x = -3
