Elden [556K]

First we define the variables:

m = multiple choice questions

s = short answer questions

Next we need to satisfy 2 conditions:

1) There are a total of 40 questions. We can represent this mathematically using the variables I defined:

m+s=40

2) The multiple-choice questions are worth 2 points and the short-answer are worth 4 points but they need to total 100 points. This can also be represented mathematically:

2m+4s=100

By satisfying the conditions provided we were able to create the 2 equations!

m+s=40

2m+4s=100
