Answer:
A) infinitely many solutions
Step-by-step explanation:
2x - y = 8
4x - 2y = 16
simplify the first equation
2x - y = 8
2x = 8 + y
2x - 8 = y
y = 2x - 8
substitute y for 2x - 8 in the second equation
4x - 2y = 16
4x - 2(2x - 8) = 16
4x - 4x + 16 = 16
4x - 4x = 16 - 16
0x = 0
since no matter what x is, 0 = 0, the answer is infinitely many solutions
