[tex]3-(x+1)=3-x-1[/tex]

[tex](+3)-(x+1)[/tex]

[tex](+3)-1(x+1)[/tex]

Distribute the -1 to (x+1)

[tex](+3)-1x-1[/tex]

[tex]3-x-1[/tex]

[tex]-x+2[/tex]

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
