Answer:
x = 5
Step-by-step explanation:
8x - 6x + 1 = 11
Add 6x to each side (because the 6 is negative)
8x + 1 = 11 - 6x
Subtract 1 from each side (because the 1 is positive)
8x = 10 - 6x
Subtract 6x from 8x
2x = 10
Divide by 2
x = 5

Answer:
28 students
Step-by-step explanation:
30% is equal to .3
40 x .3 equals 12

Another way:
Because the class has lost 30% of it's students, you know that the class is 70% of it's original capacity.
70% is equal to .7
40 x .7 is 28
