Answer 2

1)

x/72 - 13/72 = 29/72

x/72 = 29/72 + 13/72

x/72 = 42/7

x = 42

(29/42 - a) - 13/42 = 1/42

2)

29/42 - a = 11/42 + 13/42

29/42 - a = 24/42

a = 29/42 - 24/42

a = 5/42

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

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

b - 3/17 = 9/17

b = 12/17

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

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

m = 24/43 - 13/43 DZ

m = 11/43

m + 13/43 = 24/43

m = 11/43
