<h3>What is linear equation?</h3>

One or two variables make up a linear equation. Neither the numerator nor the denominator of a fraction can be a variable in a linear equation raised to a power higher than 1. All of the points on a coordinate grid sit on the same line when you identify the values that together make a linear equation true and plot those values.

<h3>According to the given information:</h3>

Let the no. of students be s:

Let the no. of books be b:

Given that there will be 20 books left after each student selects 4 books,

b = 4s + 20

And the remaining students take 5 books each, therefore b=5(s3), even if 3 pupils choose not to take a book.

comparing the value b

4s+20=5(s−3)

4s+20=5s−15

s=20+15

s=35

To do this, change the value of s in b=4s+20 to what is shown below:

b=4(35)+20

b=140+20

b=160

160 books were given to the class.
