4x+y=6 y=-4x-1 HELP ME

Mathematics
1 answer:
Afina-wow [57]2 years ago
4 0

Answer:

  • No solution

Step-by-step explanation:

<u>Given</u>

  • 4x+y=6
  • y=-4x-1
<h3>Solution 1</h3>

<u>Substitute y in the first equation:</u>

  • 4x + (-4x - 1) = 6
  • 4x - 4x =6 + 1
  • 0 = 7

Incorrect, therefore no solution

<h3>Solution 2</h3>

<u>Writing both equation as lines:</u>

  • y = -4x + 6
  • y = -4x - 1

As we see both lines have a same slope. It means they are parallel and no intersection.
