Select all of the equations that are equivalent to 3.2 + 6 = 27 3x=21
3.x=33
X+ 6 = 24
x + 2 = 9

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:

10.4 inches
