Question

Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 29 proble
worth either 5 points or 2 points. Write a system of equations that can be used to find how ma
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
x + y = 29, 5x + 2y = 100
O x + y = 100, 5x + 2y = 29
5x + y = 29, 2y + x = 100
2x + y = 100, 5y + x = 29
