5b + 11 - 2b = 3b + 11
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?
All the terms in b add to 11, so 11b = 132 making b = 12
5+3b? :3
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
b=7
=2b
a + 2b = c a = c - 2b

5b + 11 - 2b = 3b + 11
2s-2b= a+b+c-2b simplified that would be a+c-b.
If: a = 2b+c Then: a-c = 2b And: b = (a-c)/2
If this was b exponent 2 (squared) or b^2 for the first b, then it is a quadratic expression. b^2 + 2b - 11 = 88 b^2 + 2b - 99 = 0 (b+11)(b-9) = 0 B = -11 or 9

a = 2b + c then a - 2b = c ie c = a - 2b
