Answer:

9 blocks

Step-by-step explanation:

The total of what John has already walked and the number more he must walk will be equal to the number he has to walk to get to school.

12 + more = 5 + 9 + 7

more = 9 + 5 + 7 - 12 . . . . . subtract 12 from both sides

more = 9

John must walk 9 blocks more.

_____

We recognize that 5+7 = 12, so that last part of the sum totals zero.
