Answer 2

for christmas steve bought 5 more cds than dvds as presents for his freinds. he bought 21 in all . how many cds did he buy?

Answer 3

means number of cd together with dvd is equal to ---------how much

Answer 4

If you write these as equations, it helps in the analysis.
CD=DVD+5
CD+DVD=21

CD=21-DVD
21-DVD=DVD+5
16=2DVD
DVD=8

Which means CD=13.
We then check if the solution satisfies the original equation. 8+13=21 and there are 5 more CDs than DVDs
:)

Answer 5

So CDs = DVDs + 5
CDs + DVDs = 21
Substitute.
DVDS + 5 + DVDs = 21
2DVDs = 16
DVDs = 8
CDs = 13
