Answer:

6x - 24y

Explanation:

Expand -3(10x + 4y): -30x - 12y

= [tex]\bold{-30x-12y+6\left(6x-2y\right)}[/tex]

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

= 6x - 24y

Mordancy.

For this case we must simplify the following expression:

[tex]-3 (10x + 4y) +6 (6x-2y)[/tex]

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

[tex]- * - = \\- * + = -[/tex]

So, we have:

[tex]-30x-12y + 36x-12y =[/tex]

We add similar terms:

[tex]-30x-12y + 36x-12y =[/tex]

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

[tex]6x-24y[/tex]

ANswer:

[tex]6x-24y[/tex]
