Question 158067: - 3/x + 10 = x - 10/25

You can put this solution on YOUR website! - 3/(x + 10) = (x - 10)/25
I just got back home from work.
You can cross-multiply or find the LCD to find x.
If we cross-multiply, this is what it looks like:
-3 times 25 = (x + 10)(x - 10)
-75 = x^2 - 100
Add 100 to both sides.
-75 + 100 = x^2
25 = x^2
Take the square root of both sides.
5 = x
