Which system of equations has the same solution as the one above ?

Ber [7]

Answer:

x+4y=-35

-8x-4y=28

Step-by-step explanation:

The answer to the original equations is (1, -9). You can solve that by using substitution by moving the 4y over and substituting that equation for x on the second part of the top equation. Using elimination, the second set of answers will give you the same, (1, -9)!
