If a is equal to the sum of band c, what is the difference of band c?

In terms of b and a
In terms of c and a

2b -a

a-2c

Step-by-step explanation:

a = b+c

We want to find b-c

Solve the first equation for b

b = a-c

and for c

c = a-b

b-c in terms of b and a  

using c = a-b

b - (a-b)

Distribute the minus sign

b - a +b

Combine like terms

2b -a

b-c in terms of c and a  

using b = a-c

(a-c) -c

a-c -c

Combine like terms

a-2c
