Answer:
=>2x + 3y = 13..........................(1)
=>3x - 2y = 13...........................(2)
Multiplying 2 with equation (1) we get..
=>4x + 6y = 26................(3)
and multiplying 3 with (2) we get
=>9x - 6y = 39.................(4)
Adding (3) and (4) we get......
=>4x + 6y + 9x -6y = 65...
=>13x = 65
=>x = 5
