Answer:

$\huge\bold{\underline{\underline{Question}}}$ ${\implies}$

Add 8xy + 4yz - 7zx, 6yz + 11zx - 6xy & -5xz + 6yz - 2yx

$\huge\bold{\underline{\underline{Answer}}}$ ${\implies}$

=8xy - 6xy - 2xy + 4yz + 6yz t 6yz - 7zx + 11zx - 5zx

=xy(8-6-2) + yz (4+6+6) + zx(-7+11-5)

=xy(0) + yz(16) + zx(-1)

= 0 + 16yz - 1zx

Or

=16yz - zx
