I'm assuminng you want to find x and y


eliminate

hmm
eliminate y's
3 times 2=6

multiply first equation by 2 and 2nd by 3 and add

16x-6y=-32
15x+6y=-123 +
31x+0y=155

31x=155
divide both sides by 31
x=5
sub back

5x+2y=-41
5(5)+2y=-41
25+2y=-41
minus 25 both sides
2y=-66
divide by 2
y=-33


(x,y)
(5,-33)
