Expert Answer
2 a x + 3 b y = ( a + 2 b ) ...................... (1)
3 a x + 2 b y = 2 ( a + b ) .......................(2)
eqn.(1) × 3 gives , 6 a x + 9 b y = 3 a + 6 b .......................(3)
eqn.(2) × 2 gives , 6 a x + 4 b y = 4 a + 4 b .......................(4)
Eqn.(3) - Eqn.(4) gives , 5 b y = 2 b - a , hence y = ( 2 b - a ) / (5 b )
By substituting y in eqn.(1) , we get x = ( 4a + 2b ) / ( 5a )
