Kevin ran 4 miles more than Steve ran.

How many miles did Kevin run ? We don't really know, so give the "answer" a name (people usually use x or y or z).
what name do you want to use for the number of miles kevin ran ?

Answer 3

x

Answer 4

Answer 7

now you read this
Kevin ran 4 miles more than Steve ran.

the number of miles (for Kevin) is 4 more than miles for Steve
replace the words "number of miles for Kevin" with the name
replace "is" with = (an equal sign)
replace "4 more than" with 4+
replace "miles for Steve" with the name ( "y" in this case)
can you do that ?
