Expert Answer
3x - 5 y = 4 .................... (1)
9x - 2y = 7 ....................(2)
By multiplying eqn.(1) by 3
9 x - 15 y = 12 ................(3)
By subtracting eqn.(2) from eqn.(3) we get
-13y = 5 or y = - 5/13
By substituting y = -5/13 in eqn.(1) , we get
3 x = 4 - (25/13) = 27/13
x = 9/13
-----------------------------
Hene solution to eqn.(1) and (2) is
x = 9/13 ; y = -5/13
