The original rope is 25 feet in length. Two pieces are dependant on the value of , so we must first find that. The equation for the length of rope is:
The terms with can be combined:
Now, take 4 from both sides:
And divide by 7:
Now we just use the value found for to find the lengths of the rope:
To check the answer, we can make sure the three lengths sum to 25 feet:
Which it does. So the three lengths are 12 feet, 9 feet and 4 feet.
