That's an equation where x = 5

x = 8

3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.

9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5

8x - 7 = 15 + 19xsubtract 19x from both sidesadd seven to both sides8x -19x = 15 +7-11x = 22divide both sides by -11x = -2

That's an equation where x = 5

8x - 9 = 11x + 12 8x = 11x + 21 -3x = 21 x = -7

x = 8

8x - 5 + 3x + 17 = 155% 11x + 12 = 1.55 11x = 1.55 - 12 = -10.45 x = - (10.45/11) = - 0.95
