x+4y = -10 (multiply this wholly by 4) 4x-3y = -2 => 4x + 16y = -40. 4x - 3y = -2 On subtracting we get 4x + 16 y - (4x - 3y) = -40 - (-2) OR 19y = -38. I would advise you to try on yourself from here. :)

Nope y = -2. Use y = -2 in x+4y = -10, x + 4(-2) = -10, x - 8 = -10 => x = -2. Ans = (-2,-2).
