**MathMate**, Thursday, August 6, 2009 at 10:31pmFirst you define the variable,

let x be the length of the first piece in inches.

Then make an equation using the variable to represent the given relations:

x + (x+6) + (x+6)+6 = 72

Collect like terms:

3x + 18 = 72

Solve for x:

3x = 72 - 18 = 54

x = 18

Finally, verify the answer using the given relations.

First piece = 18 inches

second piece = 24 inches

third piece = 30 inches

Total = 18+24+30 = 72 inches

The solution is correct.
