Question

Simplify the expression below -3(10x + 4y) + 6(6x − 2y)

Answer 1

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:

$6x-24y$

Answer 2

Answer:

6x - 24y

Explanation:

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

= $\bold{-30x-12y+6\left(6x-2y\right)}$

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

= 6x - 24y
