Question

u - 2= 2 how to solve it

Answer 1

U-2=2
 You're going to try to leave the variable alone, so subtract 2 from both sides.
U-2=2
  +2=+2
U=4

Answer 2

Hi there!

u - 2 = 2

Since this is u subtracted from 2 then add the 2 and the answer to figure out what u is
2 + 2 = 4
Replace u with 4
4 - 2 = 2

That seems about right.

Hope this helps!
