it's simple mate just multiply the first equation with 112 and other with 67.
112×67x + 112×112y = -89×112
7504x+12544y = 9968....................(1)
112×67x +67×67y = -269×67
7504x + 4489y = 18023..................(2)
(1)-(2)
8055y = -8055
y = -1
put in any one equation given initially
67x-112 = -89
67x = 23
x = 23/67
