This is an easy one. A 2x4 is cut into three pieces,

The first piece is 3 inches longer then the third piece.

The seconded piece is 2 inches shorter than the third piece.

The three pieces together measure 1 inch over one yard.

How long is each piece?

Algebra says:

Let x = 3rd piece. Therefore...

x+3 = 1st piece, and

x-2 = 2nd piece. So...

x + x+3 + x-2 = 37

3x + 1 = 37

3x = 36

x = 12

x+3 = 15

x-2 = 10

So the length of the three pieces are 15, 10, and 12 inches.

Omg why don't just state a number in stead of saying "1 inch over one yard" , inches / yards / feet don't make sence to everyone. The puzzle is easy, I just don't know what number to use for "1 inch over 1 yard".

[b]Spoiler[/b] for [i]solution[/i]:

x + x + 3 + x - 2 = y

3x + 1 = y

piece 3 = x = (y-1)/3

piece 1 = x + 3 = ((y-1)/3)+3

piece 2 = x - 2 = ((y-1)/3)-2

Hmm i can't even edit my own reply, strange. So here is my addition to my previous post.

edit: What i want to say is: '1 inch over a yard' isn't really working as a number, also i could transform this to a distance in lightyears if I wanted to. You didn't say how you want your answer, metrics system, feet / inches. I guess that makes it safe to use Y in stead of a number.
