5x + 5 = 0
*Subtract 5 from both sides*
5x = -5
*Divide by 5 from both sides to isolate your variable x*
x = -1
*Subtract 5 from both sides*
5x = -5
*Divide by 5 from both sides to isolate your variable x*

I'm sorry, its suppose to be square root 5x+5-5=0

If you mean sqrt(5x) + 5 - 5 =0,
the +5 -5 cancels out and you get
sqrt x = 0 and x = 0.
If you mean sqrt(5x+5) -5 = 0, then rewrite it as
sqrt(5x+5) = 5
Now square both sides:
5x+5 = 35
5x = 20
x = 4
Proper use of parentheses is important.
