Question

Given the formula a=b+c, rewrite the formula to solve for b.

Answer 1

b=a-c

Explanation:

Answer 2

a=b+c
This type of problem can be done in multiple ways.
Start by subtracting b from both sides
a-b=b-b+c

Now we have:
a-b=c

Subtract a from both sides:
a-a-b=c-a

Now we have:

-b=-a+c

Divide both sides by -1 (because we have -1b)

Final answer:
b=a−c
