This may be confusing to some, just a heads up.
7 - 10 = - 3 since you have to use the negative numbers. 10 - 7 = 3 so 7 - 10 = -3.
It sounds a little confusing the way I explain it...
X represents the amount of weeks:
7+x for Germany and 3+2x for Tony they have to be equal for them to run the same distance:
3+2x=7+x
-3 from each side:
2x=4+x
-x from each side:
x=4
They run the same distance on the fourth week, that distance is 7+4=11
Hope this helps :)
