To determine Mario's present age, we can set up an equation based on the information given.
We know that Mario's current age is \( x \) years. In 7 years, he will be \( x + 7 \) years old. According to the problem, in 7 years, he will be 19 years old.
We can set up the equation as follows:
\[ x + 7 = 19 \]
This equation can be used to determine Mario’s present age.
