Решите уравнение:

17 8/25 - (18-h) = 7 18/25

1 21/70-7x/70+30/70=1 23/70

17 8/25 - (18-h) = 7 18/25

18-h=17 8/25-7 18/25

18-h=16 33/25-7 18/25

18-h=9 15/25

h=18-9 15/25

h=17 25/25-9 15/25

h=8 10/25

h=8 2/5

1 21/70-7x/70+30/70=1 23/70

-7x/70=1 23/70-1 21/70-30/70

-7x/70=-28/70

x=-28/70 * (-70/7)

x=4

18-h=17 8/25-7 18/25

18-h=16 25/25+8/25-7 18/25

18-h=16 33/25-7 18/25

18-h=9 15/25

18-h=9 3/5

h=18-9 3/5

h=17 5/5-9 3/5

h=8 2/5

91/70-7 х/70+30/70=93/70/*70

91-7 х+30=93

-7 х=93-91-30

-7 х = - 28

х = - 28: (-7)

х=4
