3(7 - 9x) - 5(5x + 1) = -8(9x - 4)     Use the Distributive Property
  21 - 27x - 25x - 5 = -72x + 32    Combine like terms (21 and -5 , -27x and -25x)
                 16 - 52x = -72x + 32    Add 72 to both sides
                 16 + 20x = 32              Subtract 16 from both sides
                        20x = 16               Divide both sides by 20
                            x = [tex] \frac{16}{20} [/tex]   Simplify the fraction
                            x = [tex] \frac{4}{5} [/tex]
