such that the result is 19a-6b+ 1aUWhat should be subtracted from the sum of3p + 4q-9r and 3r+13q-8p such that theresult is 2p+ 2q + 2r?9.

Answer»

sum =3p+4q-9r+3r+13q-8p=-5p+17q-6rhence to get the resultxp+yq+zr-(-5p+17q-6r)=2p+2q+2rhenceX+5=2,X=-3y-17=2,y=19z-6=2,z=8hencethe expression will be -3p+19q+8r

i want another method
