Simple...
you have: [tex] \frac{z}{12} =9[/tex]
To solve this..you want to isolate the variable (z)...
1.) Cancel out the 12 by multiplying it out--->>>>
[tex]12* \frac{z}{12} =9*12[/tex]
Leaving you with....
z=108
Then-->>>
5*g=230
Again, isolate the variable....
1.) Do this by dividing both sides by 5.....
5*g=230
[tex] \frac{5*g}{5} = \frac{230}{5} [/tex]
g=46
Thus, your answer.
