A drama class has a total of 26 students. The number of females is 16 less than the number of males. How many males and how many females are in the class?

The class is made up of male and female students.

"A drama class has a total of 26 students"

f + m = 26

"The number of females is 16 less than the number of males"

f = m - 16

Substitute the second equation into the first.

m - 16 + m = 26

- combine like terms -

2m - 16 = 26

- add 16 to both sides -

2m = 42

- divide by 2 -

m = 21

Now substitute that answer into either equation

f + 21 = 26

- subtract both sides by 21 -

f = 5

Remember that whatever you do to one side, you have to do to the other
