Question 489952
d+7+2(d+7)+3d+d+1=182 i was tryin to help my niece with her work but its been awhile since i took algebra so yea... the question goes like this. 
-----------------------------------------


five friends have 182 dvds.. dan has the fewest. donna has 7 more than dan betty has twice as many as donna jerry has 3 times as many dan and kenesha has 6 less than donna..
--------
Equations:
da + do + be + je + ke = 182
do = da + 7
be = 2*do
je = 3*da
ke = do-6
======================
Substitute to get:
do-7 + do + (2do) + 3(do-7) + (do-6) = 182
---
8do -7-21-6 = 182
8do - 34 = 182
donna = 27
-----
dan = do-7 = 20
betty = 2do = 54
jerry = 3*20 = 60
kenesha = do-6 = 21
