Answer:
2t + 4f = 100
t+f =42
Step-by-step explanation:
t= two point questions
f =four point questions
2t + 4f = 100
t+f =42
there are 34 two point questions and 8 four point questions
to solve multiply the second equation by -2
-2t -2f = -84
add this to 2t +4f = 100
2t + 4f = 100
-2t -2f = -84
-----------------------
2f = 16
divide by 2
f = 8
there are 8 four point questions
t+f=42
t+8 = 42
subtract 8
t = 34
there are 34 2 point questions
