Hello i really need help could you please stop by and help me?

Subtract 3y from the first equation to get x = -3y - 4

Substitute x into the second equation to get -9y - 12 - 7y = 36

Simplify: -16y - 12 = 36   -->   -16y = 48   -->   y = -3

Solve for x using the first equation: x = 9 - 4 = 5

Your answer is ( 5 , -3 )
