Answer :
Answer:
Julio is 23 years old.
Grandpa is 69 years old.
Step-by-step explanation:
To solve this equation you would make Julio and his grandpa a variable.
Now you would have one equation. (g = grandpa, J = Julio)
The equation for this would be g = J x 3
But the question states that the sum of their age is 92.
So we need another equation which is g + J = 92
so now we have g = J x 3
g + J = 92
We have to substitute g in the top equation to find out J.
Now the equation is J x 3 + J = 92
We simplify the problem and it is 4J=92
Then we divide 4 by 4 and 92 by 4 and that is 23
Now we find grandpa's age. We do this by putting Julio's age in the equation above g = J x 3
This would be g = 23 x 3
Now we multiply 23 and 3 and this is 69.
Our answers are J = 23 and G = 69
