A 90 foot rope is cut into two pieces so that the longer piece is 5 feet more than three times the shorter piece. Find the length of both pieces.

Step 1. Let x be the shorter piece and let 3x+5 be the longer piece.

Step 2. Adding the two pieces will give 90 ft or x+3x+5=90.

Step 3. Solving will yield the following steps

With x=21.25 feet, then 3x+5=68.75 feet. Note that the two pieces add up to 90 feet.

I hope the above steps were helpful.
