I am going through a past exam paper, and just don't know how to easily work out this kind of question (HIGHER TIER). It is question 2, so there must be some logical way of working it out and it is worth 4 marks.

Q2:

Nassim thinks of a number.

When he multiplies his number by 5 and subtracts 16 from the result, he gets the same answer as when he adds 10 to his number and multiplies that result by 3.

Find the number Nassim is thinking of.

? I am confused, can anyone help ?
