Answer:

  • No solution

Step-by-step explanation:

Given

  • 4x+y=6
  • y=-4x-1

Solution 1

Substitute y in the first equation:

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

Incorrect, therefore no solution

Solution 2

Writing both equation as lines:

  • y = -4x + 6
  • y = -4x - 1

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