If 3g>-36, I would suggest dividing over the least common factor or LCF. Here, it is obviously 3 (as in 3g), so divide 3g by 3, you get g. Divide -36 by 3, you get -12. So the simplified form here is g>-12. There's no real answer here, as the equation has no equal sign, only a greater than sign. G is simply greater than -12.
