2 points

4xy - 5y - 8 = 0

√2x - √5y = 16

0x + 6y - 3 = 0

4/x + 5/y = 4​

Answer 1

Answer:

The answer is 4/x + 5/y = 4

Step-by-step explanation:

$Let \: we \: take \: \frac{1}{x} \: as \: p \: and \: \: \frac{1}{y} \: as \: q$

$We \: get \: the \: equation \: as,$

$4p \: + \: 5q \: = \: 4$

$So \: we \: get \: the \: equation \: as \: a \: linear \: equation \: in \: two \: variables.$

$Therefore, \: the \: answer \: is \: \: \frac{4}{x} \: \: + \: \: \frac{5}{y} \: \: = \: 4$
