Answer:
x + y = 29, 5x + 2y = 100
Step-by-step explanation:
First, create an equation based on how there are 29 problems on the test.
x + y represents all of the questions on the test, so it should be set equal to 29.
The first equation is x + y = 29.
Now, create an equation based on how the test is worth 100 points.
5x will represent the points from the questions worth 5 points, and 2y will represent the points from the questions worth 2 points.
These terms will be added together, and set equal to 100.
The second equation is 5x + 2y = 100.
So, the system of equations is x + y = 29, 5x + 2y = 100
