1) 32 - x = (9)18/35, x = 32 - (9)18/35; (31)35/35 - (9)18/35 = (22)17/35
2) (5)11/30 - y = (3)19/30 - (7)7/30
(5)11/30 - y = - (3)3/5
y = (5)11/30 + (3)3/5 = (8) 29/30
3) x - (1)9/17 = (5)5/17 - (2)14/17
x - (1)9/17 = (4)22/17 - (2)14/17
x - (1)9/17 = (2) 8/17
x = (2)8/17 + (1)9/17
x= (3)17/17
x = 4
