Simple ...

you have:

3 (x+1) = - 2 (x-1) + 6

To even begin ... substitute and get rid of the parentheses ...

3x+3 = - 2x+2+6

3x+3 = - 2x+8

Now you can isolate the variable ...

3x+3=-2x+8

+2x + 2x

5x+3=8

5x+3=8

-3 - 3

5x=5

x=1

Check your answer ...

3 (1+1) = - 2 (1-1) + 6

3 (2) = - 2 (0) + 6

6=0+6

6=6

You know your correct ...

Thus, your answer.
