Ede4ka [16]

Let x represent number of wrong questions answered by Aaron.

We have been given that Aaron is taking a multiple choice test with a total of 20 points available. Each question is worth exactly 1 point. We are asked to find Aaron's score (out of 20) if he got 6 questions wrong.

To find Aaron's score, we will subtract number of wrong answers from total score.

\text{Aaron's score}=\text{Total score}-\text{Number of wrong answers}

\text{Aaron's score}=20-6

\text{Aaron's score}=14

Therefore, Aaron's test scores would be 14 out of 20.

To find Aaron's score if he got x questions wrong, we will subtract x from total scores that is 20-x.

Therefore, Aaron's score would be  20-x, if he got x questions wrong.
