**Tommy**, Sunday, November 4, 2007 at 10:16am5x + 5 = 0

*Subtract 5 from both sides*

5x = -5

*Divide by 5 from both sides to isolate your variable x*

x = -1

**drwls**, Sunday, November 4, 2007 at 11:40amIf 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.
