=\ln\left(7^{x-3}\right))
\ln\left(4\right)=(x-3)\ln\left(7\right))
+2\ln\left(4\right)=x\ln\left(7\right)-3\ln\left(7\right))
-x\ln\left(7\right)=-3\ln\left(7\right)-2\ln\left(4\right))
-\ln\left(7\right)\right)=-3\ln\left(7\right)-2\ln\left(4\right))
-2\ln\left(4\right)}{3\ln\left(4\right)-\ln\left(7\right)})
