ab + b = a + 2c
2*b + b = 2 + 2 * 3
3b= 8
b= 8/3

I just want to say.....YAY!!!! I just found out today that I got an A* in GCSE MAths today :):):):)
Woah, I haven't done Maths for ages but.....
What I would do is:
-substitute the values in so:
2b + b=2 +(2x3)
thus 2b + b=2 + 6
thus 2b + b=8
2b plus b makes 3b so:
3b=8
therefore b=8/3
b =2.66666666666666666667
If you then use a caluclator, eac side should equal 8 and so it works. Don't shout at me if somehow it's wrong - I haven't done maths for ages lol

(2)b+b=(2)+2(3)
2b+b=2+6
3b=8
b=3/8
