a + 2b = c a = c - 2b

3 times 6 is 18 2 times 5 is 10 18 plus 10 is 28

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?
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

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