Answer:

x = 40

Step-by-step explanation:

            15           15 • 8

   15 =  ——  =  ——————

              1        8  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

3x - (15 • 8)     3x - 120

—————————————  =  ————————

      8                                                 8    

Pulling out like terms :

  3x - 120  =   3 • (x - 40)

 3 • (x - 40)

 ————————————  = 0

      8      

 3•(x-40)

 ———————— • 8 = 0 • 8

    8    

  3  •  (x-40)  = 0

  3   =  0

  x = 40
