Urgent!!!
This is urgent.
If three fish and two portions of chips cost £6.75, and chips cost £1 less than fish, how much is fish and chips?
Yours urgently,

Re: Urgent!!!
questions belong in the help forum unless they're just for fun. Anyway, I'll assume we're talking about fixed portions.
Well if F = fish price and C = chip price, this problem states that
3*F + 2*C = 6.75
C = F - 1
two equations in two unknowns. Use substitution or elimination to solve.

A logarithm is just a misspelled algorithm.
