Question 6753
The solution is: First put all the b's on one side by subtracting the b's.
                 2b=20+b
                if you divide 2b by b you will get b
                 so if you do something to one side of the equation, do it to the other, too and you'll be ok.


like:subtract the b's from your equation

and you will have: b=20 and thats the answer

you can check by putting 20 instead of b: 2 (20) = 20 + 20 
                   40 = 40

And thats right!!!!!
