Hi,

Goal: isolate the variable on one side of the Equation

3g-6(g-8)=42   ||deal with the parenthesis FIRST

3g - 6g + 48 = 42  ||Combine Like Terms

  -3g + 48 = 42    || continue to Combine like terms (subtract 48 from both sides)

  -3g + 48 - 48 = 42 - 48

     -3g = -6      ||Finally, isolate g by dividing both sides by -3

       g = 2 

and...
