The first step for solving this expression is to distribute -2 through the first parenthesis.
x - 2xy + 2y + 4xy - x × (3 + y)
Distribute -x through the second set of the parenthesis.
x - 2xy + 2y + 4xy - 3x - xy
Now collect together the like terms with a single x as a variable.
-2x - 2xy + 2y + 4xy - xy
Lastly,, collect the like term with an xy variable to find your final answer.
-2x + xy + 2y
