Answer:
Simplified expression is 3xy + 2xz -3yz
Step-by-step explanation:
Given, xy - [yz - zx - {yx - (zy - xz) - (xy - zy)}]
= xy - {yz - zx -(yx -zy + xz) -xy + zy}
= xy - (yz - zx - yx + zy - xz -xy + zy)
= xy - (yz - xz -xy + yz -xz -xy + yz)
= xy - (3yz - 2xz -2xy)
= xy - 3yz + 2xz + 2xy
= 3xy + 2xz -3yz
