You wrote the equation.
I think you want to solve the equation for g.
-----------------
13(g+2)=78
Divide both sides by 13
g+2 = 6
Subtract 2
g = 4

To solve an equation for a variable, means to isolate the variable on one side of the equation.

13(g + 2) = 78

Whenever you see a parentheses in any math question, remove it as your first step using the distributive rule.

13 times g = 13g


13 times 2 = 26


The equation now looks this way:


13g + 26 = 78


We now subtract 26 from 78.

13g = 78 - 26


13g = 52


Lastly, we divide 52 by 13 to find g.

g = 52/13

g = 4


The answer is g = 4.
