Answer:

  • x = - 2.5

Step-by-step explanation:

  • [tex]3^{4x - 5}=(1/27)^{2x + 10}[/tex]
  • [tex]3^{4x - 5}=(1/3^3)^{2x + 10}[/tex]
  • [tex]3^{4x - 5}=(3^{-3})^{2x + 10}[/tex]
  • [tex]3^{4x - 5}=3^{-3*(2x + 10)}[/tex]
  • 4x - 5 = - 3*(2x + 10)
  • 4x - 5 = - 6x - 30
  • 4x + 6x = 5 - 30
  • 10x = - 25
  • x = - 2.5
