discussion:

a diagram is always appreciated!

assuming that

maoc = maob     + mboc       =>

108       = (3x + 4)   +   (8x - 28)     =>   combine common terms

108       = (3x + 8x) + (4 - 28 )     =>

108       = 11x - 24                         =>   add 24 to both sides

132     = 11x                                 =>

x = 132/11 = 12

so maob = 3x + 4 = 3(12) + 4 = 36 + 4 = 40

answer:

11 miles each day

step-by-step explanation:

marcus needs 80 miles a week. has already ridden 25 miles.

80-25 = 55.

marcus has 55 miles left to ride for the week and has 5 days to do it in.

assuming he rides the same amount each day:

55 / 5 = 11 miles biked each day.

check our work

5 days riding 11 miles a day would be 55 miles.

25 miles are already completed.

55 + 25 = 80
