Question from

Reevasshinie:

A watermelon with a mass of 5 kg and two durians with the same mass are placed on an electronic balance. If the reading shown on the balance is m kg, write an expression for the mass of a durian

Hi,

Suppose the mass of a durian is $d$ kg. Hence you have put a total mass of $5 + 2d$ kg on the balance. The reading is $m$ kg. This gives an equation in $m$ and $d.$ can you solve the equation for $d?$
