Question

x-y-(2x+3y+xy)+7xy+(x-3y-2xy)​

Answer 1

x-y-(2x+3y+xy)+7xy+(x-3y-2xy)

=x-y-2x-3y-xy+7xy+x-3y-2xy

=x-2x+x-y-3y-3y-xy+7xy-2xy

=-7y+4xy.

Hope it is helpful for you.

Answer 2

$\Huge\mathfrak{{\orange{a}}{\blue{n}}{\pink{s}}{\purple{w}}{\red{e}}{\green{r}}:}$

$\bf{To~solve:}$

$\sf{~~~~~~x-y-(2x+3y+xy)+7xy+(x-3y-2xy)}$

$\sf{:→ x-y-2x-3y-xy+7xy+x-3y-2xy}$

$\bf{Collecting~the~like~terms~we~get:}$

$\sf{~~~~~~(x-2x+x)+(-y-3y-3y)+(-xy+7xy-2xy)}$

$\sf{:→(0)+(-7y)+(4xy)}$

$\sf{:→\color{red}{\underline{\boxed{\bf -7y+4xy}}}}$
