Question

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?

PLEASE SOMEONE HELP.

Answer 1

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.
