Question 935144: Please help me:
State if the conclusion is correct and why or why not...
A+5=b
A+5-5=b-5
Answer by AnlytcPhil(1806) (Show Source): You can put this solution on YOUR website!

Yes, because when you start with

A+5=b

and then under that write:

A+5-5=b-5

You can justify doing that by saying either:

1. I have subtracted 5 from both sides of the equation.

OR

2. I have added -5 to both sides of the equation.
