8
Step-by-step explanation:
Using the equation in the directions (100-2x=84), we can find out how many questions Trevor got wrong on his Science test. First, we need to subtract 100-84=16 to find out how many points he lost. Trevor lost 16 points. Now we can divide 16/2=8, to find out how many questions he got wrong. Trevor got 8 questions wrong on his test.
Hope this helps!
