Answer:

{-0.5, 0.1}

Explanation:

  • multiply the 8 on the left with x/x so you can write left hand as
    (1-8x)/(x)
  • cross multiply to get rid of the fractions:
    5x = (1-8x)(5x+2)
  • simplify into a regular quadratic equation:
    -20x^2 - 8x +1 =0
  • use the quadratic formula to get the answers:


x = (8 \pm √((-8)^2 - 4 \cdot -20 \cdot 1))/(-40) = (8 \pm 12)/(-40)

so x is 20/-40 = -0.5 or x = -4/-40 = 0.1
