Question

There are 35 questions on Allison’s English test. The multiple choice questions are worth 2 points each, and the short answer questions are worth 5 points each. The entire test is worth 100 points. Let multiple question be x. And short answers be y. How many short answer questions are on the test?

Answer 1

\[\large x+y=35\\\large 2x+5y=100\]

Answer 2

2x + 5y = 100 || 35 = x + y
35 = x + y
35 - y = x
SUB...
2x + 5y = 100
2(35-y) + 5y = 100
70 - 2y + 5y = 100
3y = 30
y = 10
SUB BACK
35 = x + y
35 =x + 10
x = 25

Answer 3
