Step 1.1.2.1.1

Cancel the common factor.

$\frac{(2.9 - \log_{x} (y)) \ln (y)}{\ln (y)} = \frac{\ln (x)}{\ln (y)}$

$y = \frac{128}{x}$

Step 1.1.2.1.2

Divide $2.9 - \log_{x} (y)$ by $1$ .

$2.9 - \log_{x} (y) = \frac{\ln (x)}{\ln (y)}$

$y = \frac{128}{x}$

$2.9 - \log_{x} (y) = \frac{\ln (x)}{\ln (y)}$

$y = \frac{128}{x}$

$2.9 - \log_{x} (y) = \frac{\ln (x)}{\ln (y)}$

$y = \frac{128}{x}$

$2.9 - \log_{x} (y) = \frac{\ln (x)}{\ln (y)}$

$y = \frac{128}{x}$

Step 1.2

Subtract $2.9$ from both sides of the equation.

$- \log_{x} (y) = \frac{\ln (x)}{\ln (y)} - 2.9$

$\log_{x} (y) = \frac{\frac{\ln (x)}{\ln (y)}}{- 1} + \frac{- 2.9}{- 1}$

$y = \frac{128}{x}$

$\log_{x} (y) = \frac{\frac{\ln (x)}{\ln (y)}}{- 1} + \frac{- 2.9}{- 1}$

Step 3.1.3.3.2

Multiply $29$ by $0.1$ .

$\log_{x} (\log_{- \frac{\ln (x)}{\ln (y)} + 2.9} (x)) = - \frac{\log_{\frac{0.1 (- \ln (x^{10}) + \ln (y^{29}))}{\ln (y)}} (\frac{x}{{\log_{\frac{0.1 (- \ln (x^{10}) + \ln (y^{29}))}{\ln (y)}}}^{2.9} (x)})}{\log_{\frac{0.1 (- \ln (x^{10}) + \ln (y^{29}))}{\ln (y)}} (\log_{\frac{0.1 (- \ln (x^{10}) + \ln (y^{29}))}{\ln (y)}} (x))}$
