Question

Herrons formula:2S=a+b+c solve for b

Answer 1

minus a and minus c from both sides

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

Answer 2

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 $2S-a-c=b$.
