Question

Why does 3-(x+1)=3-x-1? Use the distributive property.

Answer 1

3-1(x+1) = 3-x-1

Step 1. distribute the negative sign

2(-x-1) = 3-x-1

Step 2. distribute the 3

-2x-3= 3-x-1

add 3 on both sides

-2x = 6 - x - 1

add x to both sides

-1x = 6 - 1

-1x=5

x=5

SO..... u have to plug 5 in

Answer 2

`3-(x+1)=3-x-1`

`(+3)-(x+1)`

`(+3)-1(x+1)`

Distribute the -1 to (x+1)

`(+3)-1x-1`

`3-x-1`

`-x+2`
