sorry these are some old notes same problem different letters
subtract 'a' from both sides:
P-a=a+b+c-a
P-a=b+c

Answer 8

replace the letters with numbers its much easier but the way of solving the equation is this
subtract 'a' from both sides:
P-a=a+b+c-a
P-a=b+c
subtract 'c' from both sides:
P-a-c=b+c-c
P-a-c=b
