Your teacher is giving a test worth 100 points containing 40 questions. there are two point and four point questions on the tes. how many of each type of question are on the test?

This shall be you answer2 points and y = questions with 4 points;

We solve the equation: x + y = 40 and 2x + 4y = 100;

Then, x = 40 - y;

2( 40 - y ) + 4y = 100;

80 - 2y + 4y = 100;

80 + 2y = 100;

2y = 20;

y = 10;

x = 40 - 10;

x = 30;
