Question

How do you simplify `x - 2(xy - y) + 4xy - x(3 + y)`?

Answer 1

`= color(blue)(xy − 2x +2y`

Explanation:

`x−2(xy−y)+4xy−x(3+y)`

`= x−2 * (xy) - 2 * (−y)+4xy− x * (3) -x * (y)`

`= x−2xy +2y+4xy− 3x -xy`

Grouping like terms:

`= color(blue)(−2xy +4xy-xy) +color(green)( x − 3x) +2y`

`= color(blue)(xy − 2x +2y`
