Mario is x years old in. 7 years he will be 19. Which equation can be used to determine Marios present age?

x - 7 = 19

x - 19 = 7

x + 19 = 7

x + 7 = 19

1 answer

To determine Mario's present age (x), we can set up the equation based on the information given:

In 7 years, Mario will be 19 years old. Therefore, we can write:

\[ x + 7 = 19 \]

This equation states that if we add 7 years to Mario's current age (x), we will obtain 19.

So, the correct equation to determine Mario's present age is:

x + 7 = 19
