I believe you solved for x, but did not plug it back into 7x-35 to get that segment’s length. The correct answer is 49.
I can't really tell if the question is asking about 7 or -7, so I'll give the answer for both.
A multiplicative inverse for 7 is a number you can multiply by 7 to make it equal to 1. In terms of an equation, you would get 7x = 1. We can then solve for x by dividing both sides by 7. So x = 1/7.
For -7, you would be able to solve the same equation as above just with -7 in the place of 7. You would end up with x = -1/7.
It would probably be 2 seconds per meter. Carlos is going at a speed of 2 SECONDS PER METER. (Also, I doubt that's possible.)

x > -9
