Liam thinks of a number.

He multiplies by the number 5 and the subtracts 60 from the result.
His answer equals the number he started with.
What was the number Liam started with?

so say the number he's thinking of is n, write n down, then he multiplies it by 5 which is 5n then he subtracts 60 from 5n, which is 5n-60, the question states that the answer "5n-60" is equal to the number he started with which is n, so you setup 5n-60=n and solve for n.
