Mario is X years old in seven years he will be 19 white equation can be used to determine Mario’s present age
Let's represent Mario's present age as "M". According to the given information, Mario's age in seven years will be 19. We can use the equation:
M + 7 = 19
To determine Mario's present age, we can use the equation:
Present Age = Future Age - Number of Years
Given that Mario will be 19 in seven years, we can substitute the values into the equation:
Present Age = 19 - 7
Simplifying this:
Present Age = 12
Therefore, Mario's present age is 12 years old.
To determine Mario's present age, we can use a simple algebraic equation. Let's represent Mario's present age with the variable "M". According to the information given, in seven years he will be 19, so we can represent his age in seven years as "M + 7" (M plus 7).
So, the equation can be represented as:
M + 7 = 19
To find Mario's present age, we need to isolate the variable "M" on one side of the equation. We can do this by subtracting 7 from both sides of the equation:
M + 7 - 7 = 19 - 7
Simplifying, we get:
M = 12
Therefore, Mario's present age is 12 years old.
