That is correct, making it look like this http://img522.imageshack.us/img522/5292/eq5uc.gif

Make an equation out of these numbers and symbols. You may only use each once. 2 3 4 5 + =

How about this: "The fish weighs 2 pounds. Two halves make a whole, so if the fish's total weight is the sum of 1 pound and half the total weight, the other half must also be 1"?

Then tell it again by correct use of grammar

Then it is a language problem, not a mathematical one.

It says it weighs 1, and then it says + half of that weigh. 1 + 0,5 = 1,5

More hints

Not possible http://www.cut-the-knot.org/do_you_know/3Utilities.shtml or with added rules http://www.puzzle.dse.nl/harder/gas_water_electricity_us.html or the words are the problem http://www.puzzles.com/PuzzleHelp/PuzzleHelpItems1_12.htm the reply on the third link was: "Reply: Dear puzzle ponderers: I have come up with a possible (viable) solution to the old puzzle about connecting up three houses with GAS, ELECTRICITY AND WATER. The answer lies in how the puzzle is worded. The instructions given are that in connecting the houses, no two lines can cross. Well, as water and gas are PIPES and ELECTRICITY is the only line....where is the problem? Ian (Mexico) Modified: November 29, 2005"

Thanks for reply. Long story short, it's been many years so I'm taking lower level of math before I jump into this again. Is there a program I can use to make those symbols and print out?

Example: x = √3x+7-1 x+1 = √3x+7 (x+1)² = (√3x+7)² x²+2x+1 = 3x+7 Question: Why +2x? x²-6-x = 0 Question: Why -6-x? x = -2 OR x = 3 Question: How can you see the answer will be -2 or 3?
