7(y + 3) - 2(x + 2) = 14, 4 (y - 2) + 3(x - 3) = 2
Ans: 7(y + 3) - 2 (x+ 2) = 14 --------- (1)
4(y- 2) + 3(x - 3) = 2 ----------(2)
From (1) 7y +21 - 2x - 4 = 14
On solving, we will get....
2x - 7y - 3 = 0 ------------- (3) From (2) 4y - 8 + 3x -9 =2
3x + 4y - 19 =0 ----------------- (4)
2x- 7y - 3
3x + 4y - 19
Substitute this, to get y = 1 and x = 5
∴ x = 5 and y = 1
