Solve

67x + 112y = -89
112x + 67y = -269

67x+112y=-89----i
112x+67y=-269----ii
Adding i and ii
179x+179y=-358
=>x+y=-2---I

Subtracting ii from i
-45x+45y=180
=>-x+y=4----II

Adding I and II
2y=2
=>y=1

-x=4-y
-x=4-1
-x=3
=>x=-3

Just multiply 67 in the first equation and 112 in second one. After it just solve it by elimination method
