Answer:
no solution
Explanation:
x + 2y = 4 → (1)
- 2x - 4y = 8 → (2)
multiplying (1) by 2 and adding to (2) will eliminate x and y
2x + 4y = 8 → (3)
add (2) and (3) term by term
(- 2x + 2x) + (- 4y + 4y) = 8 + 8
0 + 0 = 16
0 = 16 ← false statement
this false statement indicates the system has no solution
