thnx
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.
