Homework Statement
1/z - 1/2z - 1/5z = 10/(z+1)
This is the equation presented right after in the textbook where the author explains how to use the LCD to convert this equation into a more understood linear equation.
Homework Equations
Here is the example before this equation:
1/(1+x) + 1/(x-2) = x+3/(x^2-x-2)
The LCD is (x+1)(x-2)
This is multiplied in and then we have: (x-2)+(x+1)=x+3
then we simplify it to x=4
The Attempt at a Solution
I am having troubles, I am not sure what the LCD would be, my current thoughts are:
10z(z+1)
Please ask, if I left anything out.
