8a + 5g
-12g
It is: 12g+9g = 21g
If you're saying that: 12g-19 = 3g-31 then, Swap the sides around, getting common factors all on one side. E.G. 12g-3g = -31+19 9g = -12 g = -12/9 g = -1.333... or -4/3 Alternatively: 12g-19 = 3g-31 9g-19 = -31 9g = -12 g = -12/9 g = -1.333... or -4/3
3/2g + 1/6g = -3 9/6g + 1/6g = -3 10/6g = -3 5/3g = -3 5 = -9g g = -5/9
9g+9
49-9g = 40
9g-142g = -133
In order. 11 - 9 = 2 2 + 8 = 10 The answer is 10g
(9g - 8)(9g + 8)
9g + 2 = 39g = 1g = 1/9 = 0.111111111
9g-14=2g 7g=14 g=2
9g is not a source. If it's a good amount depends on the weight on the food which contains that amount.
