On its first three plays in a football game, the offense gains 6 yards,loses 5 yards, and then gains 7 yards. Write an equation that could be used to find y, the number of yards needed on the fourth play for the overall 10-yard gain required for the first down. Could you please help me with this question?

Thank You! have a happy new year

y=10-(1st down yards - 2nd down yards + 3rd down yards)
