Question 243086
6/z=9/z-1/11

Group like terms together as:

6/z-9/z = -1/11

Look for the LCF of the equation on the left. In this case, the LCF is Z. So you will factorise as:

6-9/z = -1/11

-3/Z = -1/11

Use cross multiplication technique to eliminate the fraction.

-3 (11) = Z (-1)

-33 = -Z

Divide both sides by the negative sign or by -1

-33/-1 = -Z/-1

and the final answer will be:

Z = 33
