2s-2b= a+b+c-2b simplified that would be a+c-b.
I ask my 11 year old son. 2b + 18 = 4b Subtract 2b form each side: 18 = 2b Divide each side by 2: 9 = b which is the same as b = 9, but you knew that, didn't you?
Y = 2bx divide both sides by 2b Y/2b = x
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals". There is no visible symbol between " ... equals 4" and "2b plus 1".
If: a = 2b+c Then: a-c = 2b And: b = (a-c)/2
c= a-2b
a-2b=c
a = 2b + c then a - 2b = c ie c = a - 2b
=2b
a + 2b = c a = c - 2b
A = 2b + cSubtract 'c' from each side:A - c = 2bDivide each side by 2:b = 1/2 (A - c)

b= 1/2 (a - c)
This is the same as: 13-2b = 21 -2b = 21-13 -2b = 8 b = -4
