What is the answer to this math problem?

8-0.03w = 1.72w+2.75

8 = 1.75w+2.75

5.25=1.75w

w=5.25/1.75 =3

w = 3

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:
