Answer:
g=2
Explanation:
29 - 7g = 3g + 9
move all the terms to the left, that means subtract it and set it equal to zero
29-7g-(3g+9)=0
Get rid of the parenthesis by grouping like terms together.
-7g-3g-9+29=0
Add all the numbers and variables.
-10g=-20
Divide by -10 on both sides
-10g/-10=-20/-10
Which gives you g=2
