Hello students, welcome.
00:02
We have a question here and we need to find the number of positive integers and the equation is here as x1 plus x2 plus x3 is each center 8.
00:18
So we need to check how many positive integers will be.
00:23
So let's find out the solution for the question into the solution as let's take x1 is equal to 1 plus 3.
00:36
And here a is greater than or equal to z.
00:41
X2 will be as 1 plus b and here value for b is greater than or equal to c.
00:48
Similarly x3 will be equal to 1 plus c which is c is greater than or equal to c.
00:56
So a b c are here non -negative integers.
01:06
So from equation 1 which is given into the question, let's take this as equation 1.
01:18
We will put all the values.
01:19
So x1, x2 and x3 into this equation.
01:23
So let's take our equation, x1 plus x2 plus x3 is here as 80.
01:29
So when you put down the values.
01:31
Put the values here.
01:33
1 plus 8 added by 1 plus c added by 1 plus c will be equal to 18.
01:41
Therefore, a plus b plus c will be equal to 18 minus 3...
