1) (1 1/12 + 3,75) - (-х) = 4,5
(1 1/12 + 3 3/4) + х = 4 1/2
(1 1/12 + 3 9/12) + х = 4 1/2
4 10/12 + х = 4 1/2
4 5/6 + х = 4 3/6
х = 4 3/6 - 4 5/6
х = - 2/6
х = - 1/3
2) - (5 2/3 - 1,6) - х = 6 1/3
- (5 2/3 - 1 3/5) - х = 6 1/3
- (5 10/15 - 1 9/15) - х = 6 5/15
- 4 1/15 - х = 6 5/15
х = - 4 1/15 - 6 5/15
х = - 10 6/15
х = - 10 2/5
