Now we use the following `log(x/y)=logx-logy.`
` ` `log((5x-1)/(x+7))=0`
Now we use the following `logx=0=>x=1`
`x=2` <--Your solution
This can only be solved numerically and approximate solution is `xapprox1.144`
What does `IN` mean?
This equation can only be solved numerically and approximate solution is `xapprox1.292` ` `
When trying to find numerical solution you can use many different methods, but since these are differentiable and monotonically increasing functions probably the fastest method would be Newton-Raphson method.
