2/9=x/72 144=9x 16=x
-9x - 10 = 62 -9x = 72 x = -8
If: x+16 = 9x then x = 2
x=-7
9X=4 gives x=4/9
9x+18 = 180 9x = 180-18 9x = 162 x = 18
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
Divide both sides of the equation by x: x2 = 9x x2 / x = 9x / x x = 9

9x+6=51 9x = 45 x= 5 9x-6=51 9x = 57 x= 6.33
9x + 8y = (9 x 6) + (8 x 3) = 54 + 24 = 78
