Answer:

7(x+1)+4-4=2

We move all terms to the left:

7(x+1)+4-4-(2)=0

We add all the numbers together, and all the variables

7(x+1)-2=0

We multiply parentheses

7x+7-2=0

We add all the numbers together, and all the variables

7x+5=0

We move all terms containing x to the left, all other terms to the right

7x=-5

x=-5/7

x=-5/7
