The first equation can be simplified by divide no through by 2:
4x+4=-3y+3 and it simplifies further:
4x+3y=-1.
Rearrange the second equation: 10x-9y=-8.
So we have:
4x+3y=-1
10x-9y=-8
Multiply the first of these by 3:
12x+9y=-3 and add to the second:
22x=-11, so x=-11/22=-½.
Use any equation to get y: 3y=-1-4x=-1+2=1. So x=-½ and y=⅓.
Check the solution by substituting into the original equations:
-4+8=-2+6=4 correct! -5=3-8 correct!
