[15 points, algebra 2] in exercises 61-68, determine whether the relation is a function. explain

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:

i found two solutions,   n = 2 • ± √3 = ± 3.4641
