Let n be the number of awards she won in softball

Then the number of awards in tennis was n + 3

And the number of awards in soccer was n + 1

And the total awards in lacrosse was 6 more than soccer = (n + 1) + 6

So the total number of awards is given by

n + (n + 3) + (n + 1) + (n + 1) + 6 = 31         simplify this

4n + 11 = 31       subtract 11 from both sides

4n = 20               divide both sides by 4

n = 5

And the number she won in tennis was (n + 3) = (5 + 3) = 8
