Step-by-step explanation:

Let the number be x and y.

According to the question :

(1) 3x=5y

3x-5y=0.....1

(2)x+y=80

[{×3} on both sides]

3x+3y=240......2

On subtracting 2 from 1,we get:

3x-5y=0

3x+3y=240

- - -

__________

-8y=-240

y=30

x+y=80

x+30=80

x=50

Therefore the numbers are 30,and 50.
