How many yards must be gained after a loss of 3 yards to have a total gain of 10 yards?

To find out how many yards must be gained after a loss of 3 yards to have a total gain of 10 yards, we can set up an equation.

Let's assume the number of yards gained after the loss of 3 yards is represented by 'x'.

Total gain = Loss + Gain

10 yards = (-3) yards + x

Now we can solve for 'x'.

To do that, we can add 3 yards to both sides of the equation:

10 yards + 3 yards = x

x = 13 yards

Therefore, in order to achieve a total gain of 10 yards after a loss of 3 yards, an additional 13 yards must be gained.
