Three times a larger number is 30 more than 5 times a smaller number. The sum of the larger number and 5 times the smaller numbe

slava [35]

3y = 5x + 30

y + 5x = 50 .......(1)

3y - 5x = 30 .....(2) - rearranging the first equation.

Add (1) and (2):-

4y = 80

y = 20
Now plug y = 20 into equation (1):-
20 + 5x = 50
5x = 30
x = 6

The 2 numbers are 6 and 20.
