y=9x=3it equals ......y= 3.334

x=-7

If x equals 10 and y equals 10, then 9x plus 8y equals 170.

9x+27 = -81 9x = -81-27 9x = -108 x = -12

10x = 9x -25 10x -9x = -25 x = -25

9x + 9 = 135 9x = 126 x = 14

9x - 8 = 46 9x = 46 +8 9x= 54 9x/9 = 54/9 x= 6

2y - 9x = 14 2y = 14 + 9x y = (14 + 9x) / 2

-9x-25=3 -9x=28 9x=-28 x=-28/9

9x+18 = 180 9x = 180-18 9x = 162 x = 18
