Решите уравнения. (29/42-а)-13/42=11/42 15/17-(b-3/17)=6/17 29/43-m+13/43=5/43

( 29/42 - a ) - 13/42 = 11/42 
29/42 - a = 13/42 + 11/42 
a = 29/42 - 24/42 
a = 5/42 
-----------------------
15/17 - ( b - 3/17 ) = 6/17 
15/17 - 6/17 = b - 3/17 
9/17 + 3/17 = b 
b = 12/17
-----------------------------
29/43 - m + 13/43 = 5/43 
42/43 - m = 5/43 
m = 42/43 - 5/43 
m = 37/43
