Question

The number of books in a class library is $\text{17}$more than $\text{3}$ times the number of students in the class. If there are total $\text{80}$ books, then find the total number of students.

Answer 1

Step 1: Form a linear equation with given information.

Let the number of students be $\text{x}$

Number of books = $\text{3x +17}$

Number.of books $\text{= 80}$(given)

$\text{3x +17 = 80}$

Step 2: Find the number of students.

$\text{3x +17 = 80}$

$\text{3x = 80 -17}$

$\text{3x = 63}$

$\text{x =}\frac{\text{63}}{\text{3}}$

$\text{x = 21}$

Hence , the total number of students is $\text{21}$.
