These are all essentialy the same so I will show how to solve one of them and leave the rest for you.

1)

3x + 2y = -2
4x - 5y = 5

Choose one abd rearrange into the form y = ... Here I will use the second.

y = -(5 - 4x)/5.

Replace y in the other equation by this:

3x - 2(5 - 4x)/5 = -2

simplifing gives x=0, which we put back into y = -(5 - 4x)/5, to find y=-1.
