Multiply top eq by 2 and bottom by 3 yielding:
4x + 6y = 34
9x - 6y = -.15
Add them together
13x = 33.85
x = 2.60
then substitute back into an original equation to solve for y.

add the equations together just like adding numbers
2x+3y=17
3x-2y=-0.5
-----------------
5x+y=16.5
move y to the other side
5x=16.5-y
divide them by 5
x=3.3 - y
which is what you want
