Question

A farmhouse shelter has 46 animals. Some are rabbits and ducks. Altogether there are 138 legs. How many of each animal is there?​

Answer 1

Step-by-step explanation:

let rabbits are in x number

then ducks are in (46-x) numbers

we know rabbits has four legs and ducks has two

so in equation,

4*x+2(46-x)=138

or,4x+92-2x=138

or,2x=138-92

or,x=46/2

then number of rabbits=x=23

so then number of ducks=46-x=46-23=23
