U=2

Answer 5

why do they both turn into -2

Answer 6

I always get mixed up with the signs

Answer 7

You Have to Get the Variable All By itself
U+2=4
-2 -2 If you are adding you have to subtract to both sides
if you are Subtracting you add to both sides

since you are adding you have to subtract To get U all by itself so
2-2=0 they cancel out
4-2=2

Since 2-2=0 now you have
U all by itself

so U=2
which you can prove by solving

(2)+2=4
