It's a simple linear equation in 'h' .
Its solution is [ h = 4 ].
The simplified expression of 10h+6-5h+3 is 5h+9
3h-5h + 11 = 17 is ------2h + 11 = 17- 11 -11____________-2h = 6___ ___-2 -2h = -3 (This is the answer.)
3h + (2h 20m) + 35m = (3+2)h + (20+35)m = 5h + 55m

27 times 3 minus 46 plus 23 equals 58.

1 1/2 plus 4 2/3 equals 5 3/5.
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
y= 3/6 which reduces to 1/2
