Question

the ratio of hydrogen and oxygen in water 2:1 setup a linear equation in two variables between oxygen and water​

Answer 1

Step-by-step explanation:

$let \: the \: common \: multiple \: be \: x$

So,

$hydrogen = 2x$

$oxygen = 1x \: or \: simply \: x$

$let \: the \: water \: be \: y$

or you can choose any alphabet,here.

$the \: linear \: equation$

$2x + x = y$

$3x = y$

$3x - y = 0$

$ans \: 3x - y = 0$
