log(5x-4)-log(x+1) = log4
 log[(5x-4)/(x+1) ] =log4
  = (5x-4)/(x+1) =4
     5x-4 =4x+4
     x = 4+4 =8 ans

HELLO DEAR,

log(5x - 4) - log(x + 1) = log4

log [ (5x - 4)/(x + 1) ] = log4
[ log(a / b) = loga - logb ]

(5x - 4)/(x + 1) = 4

(5x - 4) = 4x + 4

5x - 4x = 4 + 4

X = 8

I HOPE ITS HELP YOU DEAR,
THANKS
