Question

Ok this is really confusing

Answer 1

99=3/8g+2+12g+2
-4 -2 -2
95=3/8g+12g
95=12(3/8)g
(Divide both sides by 12(3/8))
2.96875=x
Or 3

Answer 2

99 = 3/8g + 6/8 + 12g + 24
99-24-6/8 = 3/8g + 12g - 6/8 - 24
75 - 6/8 = 3/8g + 12g
600/8 - 6/8 = 3/8g + 96/8g
594/8 = 99/8g
594 = 99g
594 / 99 = 99g / 99
6 = g
