Given :
Stephanie took a science exam that had two parts. Part 1: She got 16 questions correct, which was 4/5 of the number of part 1 questions. Part 2: She got 16 questions correct, which was 2/3 of the number of part 2 questions.
To Find :
The total number of questions on Stephanie's exam.
Solution :
Let, number of questions in Part 1 is x :

Let, number of questions in Part 2 is y :

Therefore, total number of questions on Stephanie's exam are 20 + 40 = 60.
Hence, this is the required solution.
X= 3 y=3
(3)2x+y=9
4x-3y=3
6x+3y=27
4x-3y=3
——————
10x=30

x=3
2(3)+y=9
6+y=9
-6. -6
y=3
