Directions: Using the digits 1 to 9 at most one time each, place a digit in each box to create a a system of equations with infinitely many solutions.
Hint
What does it mean for a system of equations to have infinitely many solutions? How are the coefficients related in systems with infinitely many solutions?
Answer
Many possible answers. One example is: 3x + 2y = 1
6x = 9 – 7 – 4y
6x = 9 – 7 – 4y
