You could solve this by elimination. Multiply equation (1) by -3 and equation (2) by 2 to get
-15x - 6y = -129
-12x + 6y = -60
Add both
-27x = -189 => x=189/27 = 7
Now replace x = 7 in one of the equations (say the second one)
-6(7) + 3y = -30
so
3y = -30 + 6(7) = 12 => y = 4
So the point of intersection is (7,4)
