Question

There are 24 students in Ms. Messing's class 6 more students walk to school then ride their bikes thus number of students who ride their bikes is the same as the number of students who are driven to school how many students walk to school

Answer 1

Walk = x + 6
Bike = x
Driven = x

x + x + x + 6 = 24
combine like terms

3x + 6 = 24
subtract 6 from both sides 

3x = 18
divide both sides by 3 to isolate x

x = 6

Walk = x + 6 = 6 + 6 = 12

12 students walk to school.
