Question

Решите уравнение : (29/42 - a) - 13/42 = 11/42
15/17 - ( b - 3/17) =6/17

Answer 1

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

15/17 - ( b - 3/17) =6/17
b-3/17=15/17-6/17
b-3/17=9/17
b=3/17+9/17
b=12/17

Answer 2

29/42-а-13/42=11/42 16/42-а=11/42 -а=-15/42 а=15/42 15/17-б+3/17=6/17 -б=-12/17 б=12/17
