Answer 3

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)

Answer 4

should i do the same process again to get x?@kropot72

Answer 5

@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.
