The social studies teacher is giving a test worth 80 points, and containing 34 questions. there are 2 point and 4 point questions on the test. how many of each type of question are on the test? show your work. a. list the two equations b. find each type of question

X is 2 pt questions
y is 4 pt questions
x+y=34
2x+4y=80
Multiply the top equation by -2 to use elimination technique
-2x-2y=-68
Then combine the two equations (x is cancelled out)
2y=12
y=6
If there are 6 four point questions, there must be 28 two point questions to get a total of 34 questions.

2x+10=36. x being the number of friends.
