11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4
x = -11
(3x-4)(x+5)
3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.
3x + y + 1 = 0y = - 3x - 12x - 3y + 8 = 03y - 2x - 8 = 03y = 2x + 8y = 2x/3 + 8/3-3x - 1 = 2x/3 + 8/3-9x - 3 = 2x + 8-11x = 11x = -1y = -3x - 1 = 3 - 1 = 2The graphs intersect at the point (-1, 2).
