The total yards that a football team gained is 7 yards.

Step-by-step explanation:

3 — 5 = — 2

There are 3 yards on the first play.

Then it was subtracted by 5 yards on the second play because they have lost so the total is already —2 yards.

— 2 + 9 = 7

However, they have managed to gain 9 yards on the third play.

You will just subtract the lacking 2 yards on the second play from the 9 yards they have gained in the third play so that they will have a total of 7 yards.
