Solve the following equation and show all the steps to solving.
Bumek [7]
\bf \cfrac{x}{x-2}+\cfrac{x-1}{x+1}=-1\impliedby LCD\to (x-2)(x+1)\\\\
-------------------------------\\\\
\cfrac{x(x+1)+(x-1)(x-2)}{(x-2)(x+1)}=-1
\\\\\\
x^2+x+x^2-3x+2=-1(x-2)(x+1)
\\\\\\
2x^2-2x+2=-1(x^2-x-2)\implies 2x^2-2x+2=-x^2+x+2
\\\\\\
3x^2-3x=0\implies 3x(x-1)=0\implies 
\begin{cases}
3x=0\implies &x=0\\
x-1=0\implies &x=1

6 less than the product of a number and 3 is -18..what is the number?
seropon [69]
The product of a number and 3 can be represented as 3n (where n = unknown number). Then 6 less than 3n is 3n - 6. 

3n - 6 = -18
3n = -12
n = -4

Check: 
-4 x 3 = -12
-12 - 6 = -18 (this works!)
