Упростите выражения: 5/6х+1/3х= 9/19х - 5/19х= 2 1/6 х+2/3х= у-11/16у= 1 5/18х+х=

1) 5/6 * х + 1/3 * х = 5/6 * х + 2/6 * х = (5 + 2)/6 * х = 7/6 * х;

2) 9/19 * х - 5/19 * х = (9 - 5)/19 * х = 4/19 * х;

3) 2 1/6 * х + 2/3 * х = (2 * 6 + 1)/6 * х + 2 * 2/6 * х = 13/6 * х + 4/6 * х = (13 + 4)/6 * х = 17/6 * х;

4) у - 11/16 * у = 16/16 * у - 11/16 * у = (16 - 11)/16 * у = 5/16 * у;

5) 1 5/18 * х + х = (1 * 18 + 5)/18 * х + х = 23/18 * х + 18/18 * х = (23 + 18)/18 * х = 41/18 * х.
