You can find the solution two different ways. One way is by plugging in each of the possible values of z into the equation and find out if the answer is equal to -5/12. OR, you can solve the equation for Z without plugging in the possible values. Let's solve by method 2.

First, we need to subtract (2/3)Z and 1/2:

Next cross multiply the fractions on each side of the equal sign:

Add -36 to both sides of the equal sign:

Divide both sides by 48 to find the value of Z:
