put p into both
bp + ap + s-r =0
ap + bp + t-s =0
now
ap+bp = s-t
put this result into first one
t-s = s-r
2s=t+r
C is your answer.
sarangboda:
so take t-s on other side, now t will be minus and s will be plus
eq. becomes ap+bp = s-t
can you get it up to here?
yes yes i got it
thank you
good
any time
if you are satisfied with the answer then please brainlist.
if you have any further questions then feel free to ask ok?
yeah sure
