Question

Ted and Sam have new bikes and already Ted has ridden 8 miles. Sam has ridden 1 mile. If each one rides 1 mile a day, how many days will it be before Ted has ridden twice as far as Sam?
8+x = 2(1+x)
8 - 1 - 1 = 6

So easy

6
8+x = 2 + 2 x
6 = x
I have no idea what you did gtif
Or

1 + 1 = 2

8 - 2 = 6
