You should listen to the comment above - learn how to do it...
These equations are simple.
-3g+9 = 15g-9
First get the "g" to one side of the equation - you do this by adding +3g to both sides
9=18g-9
now add +9 to both sides - so a number is on one side and the "g" is on the other...
9+9 = 18g -9 +9
do the math and you get
18=18g
divide both sides by 18 and you get
1=g
Then always proof your equation:
-3x1 +9 = 15x1 -9
-3+9=+6 = 15-9 also equals 6
