20+2y)3034-2y)2ACC +24)5(3x-2y)60 – InterviewSolution

1.	20+2y)3034-2y)2ACC +24)5(3x-2y)60
Answer» x+2y=m; 3x-2y=d;1/2m+5d=-3/2, 5/4m-3/5d=61/60, 3m+13d=-9; 25m-12d=61/3; multiplying first equation -by 25 and second by 3,260d-(-36m)=-225-61; 286=-286; d/-1; m=-9-10(-1)/3=1/3, now x+2y=1/3 and 3x-2y=-1; adding 2 equations 4x=-2/3; =-1/6
