47 - 6x / 5 - ( x - 6 ) = 4 ( x - 7 ) / 15
705 - 3 × 6x - 15 ( x - 6 ) = 4 ( x - 7 )
705 - 18x - 15 ( x - 6 ) = 4 ( x - 7 )
705 - 18x - 15x + 90 = 4 ( x - 7 )
705 - 33x + 90 = 4 ( x - 7 )
795 - 33x = 4 ( x - 7 )
795 - 33x = 4x - 28
795 - 33x - 4x = - 28
795 - 37x = - 28
- 37x = - 28 - 795
- 37x = - 823
x = - 823 / - 37
x = 823 / 37
