Решите уравнения

1) x/72-13/72=29/72

2) (29/42-a) - 13/42=11/42

3) 15/17 - (b-3/17) = 6/17

4) 29/43 - (m+13/43=5/43

Х/72-13/72=29/72

х/72=29/72+13/72

х/72=32/72

х=32/72•72

х=32

(29/42-а) - 13/42=11/42

(29/42-а) = 11/42+13/42

(29/42-а) = 24/42

-а=24/42-29/42

-а=-5/42

а=5/42

15/17 - (в-3/17) = 6/17

15/17-в+3/17=6/17

-в+18/17=6/17

-в+1 1/17=6/17

-в=6/17-1 1/17

-в=-12/17

в=12/17

29/43 - (m+13/43) = 5/43

29/43-m-13/43=5/43

-m+16/43=5/43

-m=5/43-16/43

-m=-11/43

m=11/43
