Question 941620: A test has a combination of true/false questions, worth 3 points each, and multiple-choice questions, worth 11 points each. The test has a total of 20 questions and a total of 100 points. How many multiple-choice questions are on the test? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = number of true/false questions
y = number of multiple-choice questions
---
x + y = 20
3x + 11y = 100
---
put the system of linear equations into standard form
---
x + y = 20
3x + 11y = 100
---
copy and paste the above standard form linear equations in to this solver:
