6(-2g-1)=-(13g+2)6(−2g−1)=−(13g+2)

g=4

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

               6*(-2*g-1)-(-(13*g+2))=0

2.1     Pull out like factors :

  -2g - 1  =   -1 • (2g + 1)

 -6 • (2g + 1) -  (-13g - 2)  = 0  

 g - 4  = 0  

4.1      Solve  :    g-4 = 0  

Add  4  to both sides of the equation :  

                     g = 4
