How i calculate this?

Some1 who needs help:

2x - (x - 3) = 5

2x-x+3=5 and you can take it from there.

2x - (x - 3) = 5 ; open the brackets - remember the '-', so the it becomes +x+3
2x+x+3 = 5

Now it is almost too easy.

high schooler:

2x - (x - 3) = 5 ; open the brackets - remember the '-', so the it becomes +x+3
2x+x+3 = 5

Now it is almost too easy.

Asd, I just made the worst mistake. I ment -x+3
