Put the function f(x) = -x/9 - 6 in the form f(x) = b + m x

m= -1/9 and b=-6

f(x) = -6 + -1/9 x

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
