Answer: g = 5/7
=======================================================
Work Shown:
Let's move the -3/7 to the other side, to fully isolate g.
We do so by adding 3/7 to both sides (to undo the subtraction)
[tex]g - \frac{3}{7} = \frac{2}{7}\\\\g - \frac{3}{7}+\frac{3}{7} = \frac{2}{7}+\frac{3}{7}\\\\g = \frac{2+3}{7}\\\\g = \frac{5}{7}\\\\[/tex]
Luckily all of the denominators are the same (7), so we can add the fractions by adding the numerators to place that sum over the common denominator.
