Question

Resolver la siguiente ecuación logarítmica

log (22-x) = log x-1 

Answer 1

(22-x)= log (x -1)Log(x-1)-log(22-x)=0
log ((x-1) / (22-x))=0
(x -1)/ (22-x) = 10^0
(x-1)/(22-x)=1
x-1=(22-x)*1
x-1=22-x
x+x=22+1
2x=23
x=23/2
x=11,5

Answer 2

Respuesta:

Explicación paso a paso:

(22-x)= log (x -1)Log(x-1)-log(22-x)=0

log ((x-1) / (22-x))=0

(x -1)/ (22-x) = 10^0

(x-1)/(22-x)=1

x-1=(22-x)*1

x-1=22-x

x+x=22+1

2x=23

x=23/2

x=11,5
