Question

$The space apparent space coefficient space of space expansion space of space straight a space liquid space when space heated space in space straight a space copper space vessel space space is space straight C space and space space when space heated space in space straight a space silver space vessel space is space straight S. space If space straight A space is space the space linear space coefficient space of space expansion space of space copper comma space then space the space linear space coefficient space of space expansion space of space silver space is space$

$\frac{c + s - 3 A}{3}$
$\underline{C + 3 A - S} 3$
$\frac{S + 3 A - C}{3}$
$\frac{C + S + 3 A}{3}$

The correct answer is: $stack C plus 3 A minus S with bar below space space space space space space 3$
