please show the work
a=24+b c=4a c=4(24+b) a+b+c=180 24+b+b+4(24+b)=180 24+b+b+96+4b=180 120+6b=180 6b=60 b=10 a=24+10 a=34 c=4(34) c=136 34+10+136=180 So book a has 34 pages, book b has 10 pages, and book c has 136 pages.
a=b+24 c=4a b=a-24 a+b+c=180 sub in a,b and c into a+b+c=180 b+24+4a+a-24=180 b+5a=180 sub a=b+24 b+5(b+24)=180 b+5b+120=180 6b=180-120 6b=60 b=10 Book B has 10 pages
