Seperate the variable and the constants

(4/9)Z-(3/9)Z-(5/9)Z-9+2

simplify the constants term

-9+2=-7

So, the equation becomes

(4/9)Z-(3/9)Z-(5/9)Z-7

Now, for the variables part

(4/9)Z-(3/9)Z-(5/9)Z

Take the LCM and add

{(4-3-5)/9}Z

{(4-8)/9}Z

{(-4)/9}Z

Thus, the equation becomes

{(-4)/9}Z-7=0

(-4/9)Z=7

Z=7(9/(-4))

Z=-63/4
