Solve for y
6y+18-5y=15
y+18=15
y=-3
Plug in y to get x

If there are 21 teachers then the number of students is 14 students.
The ratio of students to teachers is 2:3 respectively. If there are 21 teachers, the number of students can be calculated by using unitary method or by proportions.
Using unitary method
It means for every 2 students there are 3 teacher's
For 3 teacher there are 2 students
for 1 teacher there are 2/3 students
for 21 teacher there are 21(2/3) students = 14 students.
By using proportions
Number of students/ number of teacher = 2/3
Number of students / 21 = 2/3
Number of students = 21x 2/3 = 14
So, there 14 students for 21 teachers.
Therefore, if there are 21 teachers then the number of students is 14 students.
