Explanation

Let Judah's age be x. Mother's age = 2x + 4. Given mother's age is 45, the equation is 2x + 4 = 45.

AI explanation

Let Judah's age be x years. Two times his age is 2x, and 4 years more than this amount is written as 4 plus 2x. Setting this equal to his mother's age of 45 years gives the equation 4 plus 2x equals 45.
