There are total 26 questions. Each correct answer will give Tamara 8 points and, each wrong one will give her -5 points.

Imagine she answered X correct answers and Y wrong answers. So, since there are 26 questions in total, our first equation would be:

X + Y = 26

Now, she scored zero so our next equation would be:

8X + (-5Y) = 0 8X – 5Y = 0

When you solve both equations, you will get

X = 10 and Y= 16

Tamara answered 10 correct and 16 wrong.
