On a science test, 2 points are deducted from a total of 100 points for each question answered incorrectly. Trevor scored an 84 on the test. The equation 100 – 2x = 84, where x represents the number of questions answered incorrectly, represents the situation. How many questions did Trevor answer incorrectly?

Just solve the given equation for 'x'

100-2x = 84       subtract 100 from both sides of the equation

-2x = -16            Divide both sides by  - 2

x = 8

 

He missed 8 questions       cheeky
