Решите уравнение 1) (2 9/59-a)-16/59=1 5/59 2) 3 4/9-(x-1 7/9)=2 2/9 3) 10 6/10-(7 3/10-y)=4 9/10 4)17 18/35-(n+4 23/35)=9

1) (2 9/59 - a) - 16/59 = 1 5/59;

(127/59 - а) - 16/59 = 64/59;

127/59 - а = 64/59 + 16/59;

127/59 - а = 80/59;

а = 127/59 - 80/59;

а = 47/59.

Ответ: а = 47/59.

2) 3 4/9 - (x - 1 7/9) = 2 2/9;

31/9 - (х - 16/9) = 20/9;

х - 16/9 = 31/9 - 20/9;

х - 16/9 = 11/9;

х = 11/9 + 16/9;

х = 27/9 = 3.

Ответ: х = 3.

3) 10 6/10 - (7 3/10 - y) = 4 9/10;

106/10 - (73/10 - у) = 49/10;

73/10 - у = 106/10 - 49/10;

73/10 - у = 57/10;

у = 73/10 - 57/10;

у = 16/10 = 8/5 = 1 3/5.

Ответ: у = 8/5 = 1 3/5.

4) 17 18/35 - (n + 4 23/35) = 9 12/35;

613/35 - (n + 163/35) = 327/35;

n + 163/35 = 613/35 - 327/35;

n + 163/35 = 286/35;

n = 286/35 - 163/35;

n = 123/35 = 3 18/35.

Ответ: n = 123/35 = 3 18/35.
