in a trivia game, you lose point for wrong answers. You answer the first 5 questions incorrectly. Your score after the 5 questions is -90. How many points is each incorrect answer worth?

5x=-90. Set up this linear equation and solve for x. Which in this case all you have to do is divide, divide 5 on both sides. 5x/5=x. -90/5=-18. X=-18. Now check your answer by plugging back into the original equation. 5(-18)=-90=-90. Checks out. Hope this helps!
