There are 18 boys in a class there are w fewer boys than girls how many students are there in the class

The Number of boys in the class is: 18

Let's call "g" to the number of girls in the class.

The problem says that there is "w" fewer boys than girls, so we have:

g-w=18

Then, the number of girls in the class is:

g=18+w

Let's call "x" to the total number of studens in the class:

x=g+18

When we substitute g=18+w into x=g+18, we obtain:

x = (18+w) + 18

The total number of studens in the class is:

x=w+36
