(1) -2x+3y=-5
(2) 3x-4y=6

Multiple equation (1) by 3 and equation (2) by 2 so the x values become -6x and 6x. We can then cancel them out by adding the equations together like this:

(1) -6x+9y=-15
(2) 6x-8y=12. +
______________
-y=-3
y=3

Now to find x you put the y=3 into any equation. I’ve chosen equation (2)

3x-4(3)=6
3x-12=6
3x=18
x=6

So the answers are y=3, x=6

Hope this helped
