Here's a hint for you to solve this! VVV

In an algebra problem like this, one of the best strategies is to translate the sentences into equations.

Let Kylie's points be K and Shaniqua's points be S.

The first sentence says: If you subtract 2 times Kylie's points from 3 times Shaniqua's points, the difference is less than 6

We can translate this into an equation of: 3S-2K <6

The second sentence says: Shaniqua scored at least as many points as nine more than 1/4 of Kylie's points

We can translate this into an equation of: K/4 + 9 ≥ S

And for the third sentence: Kylie scored fewer then 20 points

We can translate this into an equation of: K < 20

From this sentence, "Remember that in basketball you can only score whole number of points." we know that the answers are positive integers.

So, our translations get us this systems of equations:

1) 3S-2K <6

2) K/4 + 9 ≥ S

3) K < 20

You can solve these system of equations by separating them into separate cases: in other words, you can still do substitution with the variables except try doing it so that K/4 + 9 is EQUAL TO S and then K/4 + 9 IS GREATER THAN S.

Just a suggestion! Hope this helped!
