2 books and 6 magazines

Step-by-step explanation:

4b+3.5m=29

b+m=8

subtract the m from both sides

b=8-m

plug 8-m in for b in the first equation

4(8-m) +3.5m=29

32-4m+3.5m=29

subtract the 32 and combone like terms

-0.5m=-3

divide by .5

m=6

plug 6 on for m in the second equation

b+6=8

subtract 6

b=2
