Question

A coyote had 10 pups in her third litter. It was twice as many as in her second litter, and her second litter had three more pups than her first. Find the number of pups in her first litter.

How would you put that in a equation form?

Answer 1

let x be the number of pups in her first litter
in her second it has x+3 pups.
in her third 2(x+3)
now solve:
2(x+3)=10
x=2
