Question

25-3u=2u ............????????????????????????

Answer 1

25 - 3u = 2u

You need to get the variable, u, on one side of the equation. You can do this by adding 3u to both sides.

25 = 5u

Now you want to get u by itself, divide 5 off of both sides to find u.

5 = u

Answer 2

25-3u=2u
25=5u
5=u. Hope it help!
