Simplify
\bold{-30x-12y+6\left(6x-2y\right): \ 6x-24y}

= 6x - 24y

For this case we must simplify the following expression:


-3 (10x + 4y) +6 (6x-2y)

We apply distributive property to the terms of the parenthesis, taking into account that:


- * - = \\- * + = -

So, we have:


-30x-12y + 36x-12y =

We add similar terms:


-30x-12y + 36x-12y =

Equal signs are added and the same sign is placed, while different signs are subtracted and the sign of the major is placed:


6x-24y

ANswer:


6x-24y
