Answer 1

Ответ: 1) x/72 - 13/72 = 29/72

Х:72=29/72+13/72

Х=42/72*72/1

Х=42

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

29/42-а=11/42+13/42

а=29/42-24/42

а=5/42

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

-b+3/17=6/17-15/17

-b=-9/17-3/17

b=12/17

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

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

-m=-24/43+13/43

m=11/43

Answer 2

1) x/72-13/72=29/72; 29/72+13/72=42/72, x=42/72:72=42, x=42

2)(29/42-a)-13/42=11/42; 11/42+13/42=24/42, 29/42-24/42=5/42,

a=5/42

3)15/17-(b-3/17)=6/17; 15/17-6/17=9/17, 9/17-3/17=6/17,

b=6/17

4)29/43-(m+13/43)=5/43; -m+16/43=5/43, -m+16/43-16/43=5/43-16/43; -m=-11/43; -m/-1= -11/43:(-1)

m=11/43
