Jim and Tim are brothers. Jim is three years younger than Tim. If Tim's age is x then Jim's age could be represented by the algebraic expression
Given that Jim is three years younger than Tim. so, Jim's age is always three years less than Tim's age.
For example,
If Tim’s age is 12 years, his brother’s age would be 12 - 3 = 9 years.
So, if Tim’s age is x, then the expression for Jim’s age would be (x−3).
