Solving which system leads to a contradiction where there is no solution?

A. y=1/2x + 3
2x-4y = -12

B. y= 1/2x +3
x+ 4= 9

C. y=1/2x +3
x + y = 9

D. y=1/2x +3
x = 2y = -16

Answer 1

Answer:

D

Step-by-step explanation:

x = 2y = -16 ⇒ x = -16 and y = -8

→ Substitute in the other equation

(0.5 × -16) + 3 ≠ -8
