Question 27924
Pam--

Your algebra is fine, but your setup is slightly off.

So now you have 3 consecutive pages that you're adding up, x, x+1, and x+2.
(Example 30, 30+1=31, and 30+2=32.  When you add them up you get 99. Write:
{{{x+(x+1)+(x+2)=99}}}
{{{3x+3=99}}}
{{{3x=96}}}
{{{x=96/3=32}}}
Your 3 page numbers are 32, 33, and 34, which add up to 99.
