Can someone answer this really quick

NOT CONGREUNT!! There is no axiom to prove congruent.

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:

first one is a: renaming a fraction. second one is c: de-c
