Start at 0 and go back 7 yards for their loss.  You are not at -7 on the number line.
Move 12 to the right because of the gain.   It takes 7 or those 12 just to get back to zero and you can still move 5 more to the right.   You will wind up with a gain of 5 yards.  (+5)

Answer:

The result of the two plays is that the bears gained 5 yards.

Step-by-step explanation:

We can denote the lost values as negative and won value as positive.

Given is - the bears football team lost 7 yards and then gained 12 yards.

If we take the initial start point to be zero, we can calculate the resultant.

[tex]0-7+12=+5[/tex]

Or we can calculate simply :

[tex]-7+12=+5[/tex]

Hence, the result of the two plays is that the bears gained 5 yards.
