2h + 2h + 2h = 6h
- 3h - 2h + 6h + 9 = h + 9
6h 8min
22h plus 3
6h+4g
3tx + 6t + 3hx +6h = 3(tx + 2t +hx +2h) = 3[t(x + 2) + h(x + 2)] = 3(x + 2)(t + h)

h + 6h = 7h
6h 10m - 3h 45m = 2h 25m
If you mean: 6h+7 then 6*5 plus 7 = 37
It is: 11h
This is a linear equation with one unknown and can be solved as follows. 6h + 2 = 1.......subtract 2 from both sides 6h = -1............divide both sides by 6 h = -1/6.
