    ax + hy + g = 0 Dividing both sides by a gives: x + (h/a)y + g/a = 0 .....................(1) hx + by + f = 0 Dividing both sides by h gives: x + (b/h)y + f/h = 0 .....................(2) Subtracting (2) from (1) gives: (h/a)y - (b/h)y + g/a - f/h = 0 y(h/a - b/h) = f/h - g/a y = (f/h - g/a) / (h/a - b/h)

    @AravindG Yes, I recommend that you use the same process to find x. Substitution of the value for y looks to be rather more complicated.
