Simplify the Expression: x-(3x+4y) Using Algebraic Properties

First, we open the parentheses and change the sign accordingly.

Since there are only positive numbers within the parentheses, multiplying by a negative will give us negative numbers:

$x-3x-4y=$

Now we group the X factors:

$x-3x=-2x$

We obtain:

$-2x-4y$
