2 answers:
In this equations x = the number of boys in class. So we are trying to find 3/5 of 30. First cross multiply to simplify the equation.
Divide 90 by 5 in order to get the "x" by itself, and you get 18 boys. Then take the number of boys (18) and subtract it from the total number of students (30). The final answer is 12 girls.

For example, we have:
We have that we were able to add just the terms that were sharing the same variable and exponenr (x for this case).
So, we are given the expression:
Hence, the answer is:
