Answer:

The value of the formula for b is 2S-a-c=b.

Step-by-step explanation:

Consider the provided formula.

2S=a+b+c  

We need to solve the formula for b.  

Subtract both sides by a.

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

2S-a=b+c

Subtract both sides by c.

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

2S-a-c=b

Hence, the value of the formula for b is 2S-a-c=b.
