Log5+log(5x+1)=log(x+5)+1​

Answer»

log 5 + log(5x+1) = log( x+5) +1

log5 + log(5x+1) = log (x+5) + log 10

log ( 5(5x+1)) = log(( ( x+5)10))

compare

5(5x+1) = 10(x+5)

1/2 = x+5)/(5x+1)

APPLY COMPONENDO and dividendo

1+2)/(1-2) = x+5 + 5x+1)/(x+5-5x-1)

-3 = 6x +6)/( -4x +4)

-3 = 3/2. ( x+1)/( 1- x)

-2 = ( x+1)/( 1-x)

x+1 = - 2+2x

x= 3
