Answer:

No

Step-by-step explanation:

Replace 0.5 for each x, and 4 for each y, and then solve.

-2y - x = -8.5 - 2x - y = -5

-2(4) - 0.5 = -8.5 - 2(0.5) - 4 = -5

-8 - 0.5 = -8.5 - 1 - 4 = -5

-8.5 = -13 = -5

These numbers are not equal to each other, so the answer is no.

Answer:

no it isn't bestie

Step-by-step explanation:

plug in (0.5, 4) which is (x, y) into the system of equations

it only worked for the first one:

-2(4) - 0.5 = -8.5

-8 - 0.5 = -8.5

did not work:

-2(0.5) - 4 = -5

-1 -4 = -3, not -5
