Answer:
4
Explanation:
Five students shared 30 questions by receiving an unknown number of questions each followed by 2 questions each
Let that unknown number be x
Let the second set of questions be 10 (5x2)
5x +10=30
Subract 10 from both sides
5x = 20
Divide both sides by 5
X=4
The teacher assigned each student 4 questions each (4 x 5=20)
