Question 15523: i think this is the right place to go i am not to sure. anyways... the problem is s= b + 1/2 pl
and i am solving for l. do i first subtract b from each side then it would be
b-s=1/2pl then what do i do? if you coulod help me that would be wounderful. thank you soo much!

Well, you've got the right idea but...
Solve for l:
s+=+b+%2B+%281%2F2%29pl Subtract b from both sides.
s+-+b+=+%281%2F2%29pl Here's where you erred. You had b - s rather than s - b
Now you would divide both sides by %281%2F2%29p
%28s+-+b%29%2F%281%2F2%29p+=+l You can simplify this.
%28s+-+b%29%2F%281%2F2%29p+=+2%28s+-+b%29%2Fp
Finally:
l+=+2%28s+-+b%29%2Fp
