To solve for $y$ in the given system of equations:

1. $\ln(x) + 3\sqrt{y} = 9$
2. $x^2 - 5y = 114$

We can approach the problem step-by-step to express $y$ in terms of $x$ or find specific values for $x$ and $y$.

Step 1: Solve for $\sqrt{y}$ in terms of $x$

From the first equation: $\ln(x) + 3\sqrt{y} = 9$ Isolate $\sqrt{y}$: $3\sqrt{y} = 9 - \ln(x)$ $\sqrt{y} = \frac{9 - \ln(x)}{3}$ Square both sides to solve for $y$: $y = \left(\frac{9 - \ln(x)}{3}\right)^2$

Step 2: Substitute $y$ in the second equation

Substitute this expression for $y$ into the second equation: $x^2 - 5\left(\frac{9 - \ln(x)}{3}\right)^2 = 114$ This equation now contains only $x$ and can be simplified to solve for $x$.

Step 3: Solve for $x$ (if possible) and then back-substitute to find $y$

Once $x$ is found, substitute it back into $y = \left(\frac{9 - \ln(x)}{3}\right)^2$ to find the corresponding value of $y$.

Here are 5 questions that extend this topic:

1. How would you solve if the logarithmic equation involved a base other than $e$?
2. What would change if the square root function were replaced with an exponential?
3. How can logarithmic differentiation help in solving complex equations?
4. What role does the domain of the logarithmic function play in these types of problems?
5. How can graphing help to visually confirm the solutions to this system?

Tip: Always consider the domain restrictions when working with logarithmic and square root functions, as they affect the possible values for the variables.
