The number of boys in a class is 5 less than twice the number of girls in the class if the total number of boys is 23 find the total number of students in the class

Given: Number of boys is 5 less than twice the number of girls.

Total boys are 23

To do: Find the number of students in the class.

Solution:

Number of boys  =  $23$

Number of girls  =  $x$

Convert his into equation,

$  23   =   2 x  -  5$

rewrite,

$2 x  -  5   =  23$

$2 x  =  23  + 5$

$2 x  =  28$

$ x   =  \frac{28}{ 2}$

$ x   =  14$

So, the number of girls = 14

Total number students = Number of boys $+$ Number of girls

                                          =   $23  +  14  =  37$

So, total number students =  37
