Answer :

Let the number of miles Bill ran be X

Given that Jacob ran 7 miles less than Bill.

Since Jacob ran 18 miles, the miles Jacob ran will be represented by the equation below:

X - 7 = 18

Now let's solve for x:

First add 7 to both sides of the equation:

[tex]X\text{ - 7 + 7 = 18 + 7}[/tex][tex]X\text{ = 25 miles}[/tex]

Therefore, Bill ran a total of 25 miles
