Hello,

let m be the weight of Max;
let f be the weight of Fiffi;
let s be the weight of Sparky.

Now you can translate your sentences into equations:
1.: f+m =72
2.: m + s=86
3.: f + s=35

This is a system of linear equations and there are a lot of ways to solve it.

Never mind which one you use you should come up with this solution:
$f=\frac{21}{2},\ m=\frac{123}2},\ s=\frac{49}{2}$
