Answer:

Step-by-step explanation:

x --- 20%

What is the approximate value of x in the equation below.

fomenos

Answer: First Option

$x= -3.396$

Step-by-step explanation:

We have the following expression

$log_{\frac{3}{4}}25 = 3x -1$

To solve the equation add 1 to both sides of the equality

$log_{\frac{3}{4}}25 +1= 3x -1+1$

$log_{\frac{3}{4}}25 +1= 3x$

Divide between 3 to both sides of the equation

$\frac{log_{\frac{3}{4}}25 +1}{3}= x$

$x= \frac{-11.19 +1}{3}$

$x= -3.396$

The answer is the first option
