54 is the product of Diego's age and 3 .

product: multiply

3x = 54
solve for x

To find out Diego's age, we can use algebraic equations. Let's represent Diego's age as x.

We know that 54 is the product of Diego's age and 3. Mathematically, we can write this as:

3x = 54

To solve for x (Diego's age), we need to isolate x on one side of the equation. We can do this by dividing both sides of the equation by 3:

3x/3 = 54/3

x = 18

Therefore, Diego's age is 18 since 3 multiplied by 18 is equal to 54.
