Question

simplify: 3x-4y-xy-(2x-2y-xy)+3xy+y-x.​

Answer 1

SOLUTION

Hey mate here your solution hope you will understand it and it will help you.I am showing it step by step so that you will understand it more easily

Given expression,

$3x - 4y - xy - (2x - 2y - xy) + 3xy + y - x$

Firstly let us remove the bracket by opening the terms,

$3x - 4y - xy - 2x + 2y + xy + 3xy + y - x$

We know , we can subtract or add the like terms so on doing that we get,

$3x - 2x - x - xy + xy + 3xy+ 2y - 4y + y \\ = 3xy - y \\ = y(3x - 1)$

Here we got the answer

Answer 2

Answer:

$= > 3x - 4y - xy - (2x - 2y - xy) + 3xy + y - x \\ \\ = > 3x - 4y - xy - (2x) - ( - 2y) - ( - xy) + 3xy + y - x \\ \\ = > 3x - 4y - xy - 2x + 2y + xy + 3xy + y - x \\ \\ = > (3x - 2x - x) + ( - 4y + 2y + y) + ( - xy + xy + 3xy) \\ \\ = > (3x - 3x) + (3y - 4y) + (4xy - xy) \\ \\ = > - y + 3xy \\ \\ = > 3xy - y \\ \\ = > y(3x - 1)$
