Let's assume that the first team gets 2x units of wire, and the second team gets 5x units of wire.

According to the given information, the second team gets 10 units more wire than the first team. So, we can set up an equation:

5x = 2x + 10

Now, solve for x:

5x - 2x = 10
3x = 10
x = 10 / 3

So, the first team gets 2x = 2 * (10 / 3) = 20 / 3 units of wire. This can also be expressed as approximately 6.67 units of wire.
