# In 10-14, find how many solutions there are to the given equation that satisfy the given condition. x 1 + x 2 + x 3 = 20 , each x i is a positive integer.

To determine

To find the number of solutions to the given equation that satisfy the given condition:

x1+x2+x3=20, each xi is a positive integer.

Explanation

Given information:

x1+x2+x3=20, each xi is a positive integer.

Concept used:

The number of r combinations with repetition allowed that can be selected from a set of n elements is:

(r+n1n1)

Calculation:

The number or units in each category xi indicates the value or xi in a solution of the equation.

Each solution can be represented by a string of two vertical bars and 20 crosses.

Consider that x1+x2+x3=20
