Answer:
We have (a+2b)x+(2a−b)y=2 ...................(1)
(a−2b)x+(2a+b)y=3 ...................(2)
Adding the two we get 2ax+4ay=5 ...................(3)
and subtracting (2) from (1), we get
4bx−2by=−1 ...................(4)
Multiplying (3) by 2b and (4) by a, we get
4abx+8aby=10b ...................(5)
and 4abx−2aby=−a ...................(6)
Subtracting (6) from (5), we have
10aby=10b+a or y=10b+a10ab=1a+110b
Multipying (6) by 4 and adding to (5), we get
20abx=10b−4a or x=10b−4a20ab=12a−15b
