How to solve algebra word problem?

Let the number he starts with be x.

He multiplies by 5 and subtracts 60 from it to give x. Thus;

5x - 60 = x

We arearrange this algebra to collect like terms on same side to get;

5x - x = 60

4x = 60

Using division property of equality, divide both sides by 4 to get;

4x/4 = 60/4

x = 15
