as you are seeking an answer that says x =
you want x to be on the LHS (Left Hand Side)
so rewrite your equation
- 7x - 4 = - 2
- 7x = - 2 + 4
- 7x = 4 - 2
- 7x = 2
x = 2/(-7)
x = - 2/7

-2=-7x-4
-2 + 4 = -7x -4 + 4
added 4 to both sides to get:
2= -7x
Now divide both sides by -7 to get x by itself
- 2/7 = x
and there is your answer!

-2 = -7x - 4
add 4 for both sides
2 = -7x
divide -7 for both sides
x = -2/7

-2=-7x-4
-2+4=-7x
2=-7x
-2/7 =x

- 2 = - 7x - 4
7x = - 4 + 2
7x = - 2
x = - 2/7
Answer: x is - 2/7
Proof:
- 2 = - 7(- 2/7) - 4
- 2 = 2 - 4
- 2 = - 2
