Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 29 problems. Each problem is
worth either 5 points or 2 points. Write a system of equations that can be used to find how many problems of each
point value are on the test.
Let x be the number of questions worth 5 points and let y be the number of questions worth 2 points.
x+y = 29.5x + 2y = 100
x + y = 100, 5x + 2y = 29
5x + y = 29. 2y + x = 100
2x + y = 100.5y + x = 29
