3x - 7y + 10 = 0 can be written as 3x - 7y = - 10 .....(1)
y - 2x - 3 = 0 can be written as y - 2x = 3 .....(2)
Multiplying (1) by 2 and (2) by 3 we get,
6x - 14y = -20 .....(3)
3y - 6x = 9 ......(4)
Adding eq. (3) and eq.(4),
-11y = -11
Hence, y = 1
Using y's value in (4)
3(1) - 6x = 9
3 - 6x = 9
-6x = 6
Hence, x = -1.
