To determine Mario's present age, you can use the equation: x + 7 = 19.
Let's assume that Mario's present age is y.
In 7 years, his age will be y + 7.
According to the given information, in 7 years Mario will be 19, so we can form the equation:
y + 7 = 19
To determine Mario's present age, you need to set up an equation based on the given information. Let's denote Mario's present age as "x".
According to the information provided, in 7 years, Mario will be 19 years old. This means that in the present, Mario's age (x) plus 7 years will equal 19.
So, we can set up the equation:
x + 7 = 19
To determine Mario's present age, we solve for x. By subtracting 7 from both sides of the equation, we get:
x = 19 - 7
x = 12
Therefore, Mario's present age is 12 years old.
