Answer:

x = 128/61

Step-by-step explanation:

25 - 8x / 7x - 1 = 3 / 5

5 (25 - 8x) = 3 (7x - 1)

125 - 40x = 21x - 3

- 61x = -128

x = 128/61

Answer:

Step-by-step explanation:

(cross multiplication)

  •                                     5(25-8x)     =  3(7x-1)

                                             125-40x      =  21x -3

(underlined : cancel)         125-40x+125 = 21x - 3 +125

  •                                     -40x             =  21x + 128
  •                                     -40x - 21x     =  21x + 128 - 21x
  •                                     -19x               =  128
  •                                     -19x/19          =  128/19
  •                                                  hence,
  •                                       x                     =  129/19
