Wiring 2

Willie cut a piece of wire that was 3/8 of the total length of the wire. He cut another piece that was 9m long. The two pieces together were one half of the total length of the wire. How long was the wire before he cut it?

Correct result:

l =  72 m

Solution:


3/8 l + 9 = l/2

3/8•l + 9 = l/2

l = 72

Our simple equation calculator calculates it.
