Answer:
4 classes
Step-by-step explanation:
1. Write an equation for the cost for both members and nonmembers, in which x is the number of aerobics classes.
Cost = 3x + 6 for members
Cost = 4x for nonmembers
2. Set the equations to equal each other and solve.
3x + 6 = 4x
-3x -3x
6 = x
3. Check your answer
4*6 = 24
(3*6) + 6 = 24
For 4 aerobics classes, the cost for members and nonmembers is the same.

Answer:
m = 8
Step-by-step explanation:
8m − 2m − m − m − 2m = 16
6m -m -m -2m= 16
4m - m -m = 16
4m - 2m = 16
2m=16
2/2m = 16/2
m = 8
