Answer:
x = 9 ; y = -1
Step-by-step explanation:
because one equation is 3y and the second is -3y they will cancel out (eliminate) so the term y will be gone and you combine (add) the rest of the terms and end up with
[tex]2x=18[/tex]
then divide both sides by 2 to get: x = 9
plug in the value of x into one of the original problems
[tex]9+3y=6[/tex]
and solve for y
[tex]3y=-3\\y=-1[/tex]
if you plug in the values of x and y into the equations it should be true
