Answer:
DNE.
Step-by-step explanation:
8x - 2y = 1 ---------------------(1)
-4x+ y = 3----------------------(2)
Multiply (2) by 2
-8x +2y = 6 -----------------(3)
Add (1) to (3)
8x - 2y + (- 8x + 2y) = 1+6
8x - 2y - 8x +2y = 7
But all the terms in LHS cancel out, leaving 0.
So you get 0=7, which is not valid.
Therefore no solution exists. DNE
For the first one it’s 9490 & for the second it’s 860
