Mario is x

years old. In 7 years, he will be 19. Which equation can be used to determine Mario’s present age?(1 point)
Responses

x − 7 = 19
x minus 7 equals 19

x + 7 = 19
x plus 7 equals 19

x + 19 = 7
x plus 19 equals 7

x − 19 = 7
x minus 19 equals 7

1 answer

To determine Mario's present age based on the information given, we need to set up an equation using the fact that in 7 years, he will be 19 years old.

If Mario is currently \(x\) years old, in 7 years he will be \(x + 7\) years old. According to the problem, this expression will equal 19.

So we can set up the equation:

\[ x + 7 = 19 \]

Thus, the correct response is:

x + 7 = 19
