Julio’s grandpa is 3 times as old as he is the sum of their age is 92 how old is grandpa

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
