To determine Mario's present age, we can set up the equation based on the information given. If Mario is currently \( x \) years old, then 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 formulate the equation as follows:
\[ x + 7 = 19 \]
Therefore, the correct equation that can be used to determine Mario's present age is:
\( x + 7 = 19 \)
