Answer:

x = 1

Step-by-step explanation:

Given :

  • y = -4x - 4
  • y = -8x

Equate the sides :

  • -4x - 4 = -8x

Add 4 on both sides :

  • -4x - 4 + 4 = -8x + 4
  • -4x = -8x + 4

Add 8x on both sides :

  • -4x + 8x = -8x + 4 + 8x
  • 4x = 4

Divide both sides by 4 :

  • 4x/4 = 4/4
  • x = 1
