Answer:

g=2

Step-by-step 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
