Question

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

Answer 1

6x - 24y

Step-by-step 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

Mordancy.

Answer 2

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`
