Ben has 3 times as many guppies as goldfish. If he has a total of 20 fish, how many guppies does he have?

Guppies: u Goldfish: o
3 times as many guppies as goldfish 3*o = u (there are more guppies than goldfish)
o + u = 20 o = 20 - u
Substitute in (20 - u) for o in the first equation and solve: 3* (20 - u) = u 60 - 3u = u 60 = 4u u = 15
He has 15 guppies. Then substitute in the number of guppies into either equation to find the number of goldfish: o + u = 20 o + (15) = 20 o = 5
Hope this helps! :)

Ben has 15 guppies and 5 goldfish. We find this by setting up equations based on the relationships given in the problem. The total adds up to 20 fish, confirming our results.
