Question:-

67X +112Y = - 89, 112X +67Y = - 269

${\red{\underline{\underline{\bold{Answer:-}}}}}$

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
