х/72 - 13/72 = 29/72 х/72 = 29/72 + 13/72 х/72 = 42/72 х=42 (29/42 - а) - 13/42 = 11/42 29/42 - а = 11/42 + 13/42 29/42 - а = 24/42 а=29/42 - 24/42 а = 5/42

Accepted Answer

1) х/72 -13/72 = 29/72 х/72 = 29/72 + 13/72 х/72 = 42/72 х = 42*72/72 х = 42 2) (29/42 - а) - 13/42 = 11/42 29/42 - а = 11/42 + 13/42 29/42 - а = 24/42 а = 29/42 - 24/42 а = 5/42
