The volume of a bottle is

x

litres and the volume of a can is

y

litres.

5 bottles and 2 cans can hold 13 litres of water.
3 bottles and 4 cans can hold 17 litres of water.

Solve these simultaneous equations to find the value of

x

and of

y

$x = \dfrac{9}{7},\ y = \dfrac{23}{7}$
$x = \dfrac{23}{7},\ y = \dfrac{9}{7}$
$x = 1,\ y = 4$
$x = 2,\ y = 3$
