Question

xy-[yz-zx-{yx-(3y-xz)-(xy-zy)}]

Answer 1

yx-3y is it answer..........

Answer 2

Let's simplify step-by-step.

xy−(yz−zx−(yx−(3y−xz)−(xy−zy)))

Distribute the Negative Sign:

=xy+−1(yz−zx−(yx−(3y−xz)−(xy−zy)))

=xy+−1yz+−1(−xz)+−1(−xy)+−1(3y)+−1(−xz)+−1xy+−1(−yz)

=xy+−yz+xz+xy+−3y+xz+−xy+yz

Combine Like Terms:

=xy+−yz+xz+xy+−3y+xz+−xy+yz

=(xy+xy+−xy)+(xz+xz)+(−yz+yz)+(−3y)

=xy+2xz+−3y

Answer:

=xy+2xz−3y
