I need help solving for x: log x = 2.46 - 1.12 * log y
Mariulka [41]
\bf log_{{  a}}(xy)\implies log_{{  a}}(x)+log_{{  a}}(y)&#10;\\\\\\&#10;% Logarithm of exponentials&#10;log_{{  a}}\left( x^{{  b}} \right)\implies {{  b}}\cdot  log_{{  a}}(x)&#10;\\\\\\&#10;{{  a}}^{log_{{  a}}x}=x\impliedby \textit{log cancellation rule}\\\\&#10;-----------------------------\\\\

\bf log(x)=2.46-1.12log(y)\iff log_{10}(x)=2.46-1.12log_{10}(y)&#10;\\\\\\&#10;log_{10}(x)=2.46-log_{10}(y^{1.12})\implies log_{10}(x)+log_{10}(y^{1.12})=2.46&#10;\\\\\\&#10;log_{10}(x\cdot  y^{1.12})=2.46\implies 10^{\cfrac{}{}log_{10}(x\cdot  y^{1.12})}=10^{2.46}&#10;\\\\\\&#10;xy^{1.12}=10^{2.46}\implies \boxed{x=\cfrac{10^{2.46}}{y^{1.12}}}
