Question

Please! Determine which system below will produce infinitely many solutions.

A. 2x + 5y = 24
2x + 5y = 42
B. 3x - 2y = 15
6x + 5y = 11
C. 4x - 3y = 9
-8x + 6y = -18
D. 5x - 3y = 16
-2x + 3y = -7

Answer 1

System C

Explanation:

When we multiply both sides of the equation 4x - 3y = 9 by -2, we obtain

-8x + 6y = -18. So system C has infinitely many solutions.
