Question

Simply 7(x-2) -4x +9

Answer 1

a(b+c)=ab+bc
7(x-2)=7x-7*2=7x-14
7(x-2)-4x+9=7x-14-4x+9
=3x-5

Answer 2

For this case we must simplify the following expression:

`7(x-2) -4x+ 9`

We apply distributive property to the terms within parentheses:

`7x-14-4x+ 9`

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

`7x-4x-14+9`

`3x-5`

Answer:

`3x-5`
