I need help to find the values of "p" & "c" if:

pc=120

(p+2)(c-3)=120

My first step was to expand the brackets to get:

pc=120

pc-6-3p+2c=120

Which simplifies to:

pc=120 A

pc-3p+2c=126 B

I then take A from B which leaves:

-3p+2c=6

I am not sure what to do from this point nor am i confident it is correct up to this point. I would be very greatful for any pointers.

Thanks in advance
