Solve for x x/6=9
X=1.5
X=3
X=15
x=54

x=54

Step-by-step explanation:

Mutiply by both sides

6x/6=9x6

x=54

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:

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
