Virginia, Adrienne, and Dennis have taught history for a combined total of 96 years. If Virginia has taught for 9 more years than Adrienne and for 9 fewer years than Dennis, for how many years has Dennis taught?

Why am I wrong in my setup?

V= A + 9
A= A
D= V + 9= ( A + 9) + 9

D= A + 18

Nothing. Now that you have V, A, and D all in terms of A, is there a relationship among V, A, and D that you can use?

Yep, express everything in terms of A doesn't work out for some reason, I mean I got the answer using another algebra relationship but this one doesn't work out.

Why not?

V= A + 9
A= A
D= V + 9= ( A + 9) + 9 = A + 18

now V+A+D=96
=> (A+9) + A + (A+18) = 96
=> 3A + 27 = 96
=> 3A = 69
=> A=23

So, V=23+9=32
D= 23+18=41

If you write the question right, Denise has thaught 9 years more than Victor- So:
it shouldbe like:
V=a+9
D=v-9
so, the equation is:
a+9a+a+9-9=96
a=29
d=29
v=38

Seftalibebegim,
If Denise has taught 9 years more than Victor then D is greater than V. Hence it is D-9=V

Your, 2nd equation is not correct.
