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

What does ã5x mean, and why is there a  sign before the = sign?

I'm sorry, its suppose to be square root 5x+55=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.
