giúpppppppppppppppppppppppppppppp mìnhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh vớiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii

mình đang cần gấp

Answer 1

x/3-4/y=1/5

=> 5.x/15 - 4/y = 3/15

=>  4/y   =  5.x/15 - 3/5

=>  4/y=5.x-3/5

=> y = 5

     x = 4+3=7

còn các trường hợp khác

ủng hộ nhé

Answer 2

\(\frac{x}{3}-\frac{4}{y}=\frac{1}{5}\)

\(\frac{x}{3}+\frac{1}{5}=\frac{4}{y}\)

\(\frac{5x+3}{15}=\frac{4}{y}\)

Answer 3

cảm ơn nha
