Me with these 2 problems step by step and show work! z/12=9 what is the value of z show how you found it. 5 x g= 230 what is the value of g show how you found it. i really need !

Simple...

you have: 

To solve this..you want to isolate the variable (z)...

1.) Cancel out the 12 by multiplying it out--->>>>



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



g=46

Thus, your answer.
