Математика: Решите уравнения 1) (х - 17 1/9) - 4 5/12 = 19 17/18 2)(8 3/16 + х) - 7 3/4 = 24 7/8

gnastena021 · Answer

1) (х - 17 1/9) - 4 5/12 = 19 17/18
х - 17 1/9=19 17/18+4 5/12
х - 17 1/9=24 13/36
х= 24 13/36+ 17 1/9
х=41 17/36

2) (8 3/16 + х) - 7 3/4 = 24 7/8
8 3/16 + х=24 7/8+7 3/4
8 3/16 + х=32 5/8
х = 32 5/8-8 3/16
х = 24 7/16
