5h - 3h + 9h = 176 11h = 176 h = 16
3h+13 = 7 3h = 7-13 3h = -6 h = -2
6h 8min
-9h-6+12h+40 = 22 3h+34 = 22 3h = 22-34 3h = -12 h = -4
-9h - 6 + 12h + 40 = 22 ie 3h = 22 + 6 - 40 h= -12/3 = -4
5h - 3h + 9h = 176 11h = 176 h = 16
3h+13 = 7 3h = 7-13 3h = -6 h = -2
8h - 10h = 3h + 25-2h = 3h + 25-5h = 25-h = 5h = -5
6h 8min
-9h-6+12h+40 = 22 3h+34 = 22 3h = 22-34 3h = -12 h = -4
-9h-6+12h+40=22 -9h+12h=22-40+6 3h=-12 h=-4
-9h - 6 + 12h + 40 = 22 ie 3h = 22 + 6 - 40 h= -12/3 = -4
3h-5h + 11 = 17 is ------2h + 11 = 17- 11 -11____________-2h = 6___ ___-2 -2h = -3 (This is the answer.)
h = -5 8h - 10h = 3h + 25 -2h = 3h + 25 -2h - 3h = 3h - 3h + 25 -5h = 25 h = -5 CHECK: 8(-5) - 10(-5) = 3(-5) + 25 -40 - -50 = -15 + 25 -40 + 50 = 10 10 = 10 CORRECT
3h + 20 - h + 5 = 2h + 25
- 3h - 2h + 6h + 9 = h + 9
3h + (2h 20m) + 35m = (3+2)h + (20+35)m = 5h + 55m
