Question

ben has 4 more than twice as many cd's as jake. if they have a total of 31 cd's, home cd's does jake have ?

Answer 1

Let Jake's number of CDs be \(x\). Then Ben has \(2x+4\) CDs. Then, what's the sum in terms of \(x\)?

Answer 2

Jake = j
Ben = b
ben has 4 more than twice jake
b = 4+2j
total 31 cds
b + j =31

Answer 3

you can use subsitution to solve
b = 4+2j
b + j =31
subsitute b = 4+2j into b + j =31
(4+2j)+j=31
simplify to get
4+3j=31
3j=27
j=9
Jake has 9 CDs
b=4+2j or b=4+2(9)
so Ben has 22 CDs

Answer 4
