Write an equation, and solve An electrician has a 20-ft wire. He needs to cut the wire so that one piece is 4 ft shorter than the other. What will be the length of each piece?

12, 8

Step-by-step explanation:

So we have the following things we need to check for:

1. Both wires add up to 20 ft.

2. One wire is 4 ft longer than the other.

In order to do this we can create the following two equations (I'll call the wires a and b)

Next we substitute equation two into equation one and solve for b.

And lastly we solve equation 2 using the new value of b.

So the wires are 12 and 8 feet.

yes because they have the same amount of green and blur marbles.
