Question

How to do a=b+c plz explain there all variables and your solving for c

Answer 1

A=b+c
a-b=b+c-b
a-b=c
or
c=a-b

Answer 2

A = b + c ; Solve for c

We essentially just need to get "c" onto it's own side of the equal sign :)

So, subtract b from both sides!

a - b = b + c - b

Simplify.

a - b = c

So, c = a - b
