3x - 2y + 7x + 4y = 3x + 7x - 2y +4y = (3+7)x + (-2+4)y = 10x + 2y
5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y
6x2 = -7x -2 6x2 + 7x + 2 = 0 6x2 + 3x + 4x + 2 = 0 3x(2x + 1) + 2(2x + 1) = 0 (2x + 1)(3x + 2) = 0 2x + 1 = 0 or 3x + 2 = 0 So, x = -1/2 or -2/3
7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3
(x2 + 7x - 18) = (x + 9)(x - 2)
