u=4

Explanation:

To find the value of u, we want to isolate u, which means getting it alone on one side of the equal sign.

In order to do this, we subtract 2 from the right side. However, since the right and left sides have to be equal, we also have to subtract 2 from the left side:
6-2=2+u-2

This gives us 4=u.

To check this, we can substitute the value we found for u back into the original equation to see if it works:
6=2+4

Since this is correct, we know we were right.
