Answer:
The equation:
Where the xi are non-negative integers has 5050 solutions
Explanation:
We need to find a combination with repetitions to find how many solutions have the equation:
We know the xi are non-negative integers and we have three unknowns in the equation, so:
m= 3 (The number of unknowns in the equation)
r= 99 (result - 1)
The combination is:


The number of solutions to this equation is: 5050 solutions
