Let's solve the given problem step-by-step.

We are given the following two equations:

1. $3(27^x) = 81^y$
2. $\log_3 y = 2 + \log_3(x - 2)$

Step 1: Simplify the first equation

First, let's express $27$ and $81$ in terms of base $3$:

$27 = 3^3$ $81 = 3^4$

Substitute these into the first equation:

$3(3^{3x}) = (3^4)^y$

This simplifies to:

$3^{1 + 3x} = 3^{4y}$

Since the bases are the same, we can set the exponents equal to each other:

$1 + 3x = 4y$

Step 2: Solve for $y$ in terms of $x$

$4y = 1 + 3x$ $y = \frac{1 + 3x}{4}$

Step 3: Simplify the second equation

Using the logarithm properties, we can rewrite the second equation:

$\log_3 y = 2 + \log_3(x - 2)$

Apply the property $\log_b(m) + \log_b(n) = \log_b(mn)$:

$\log_3 y = \log_3 3^2 + \log_3(x - 2)$

$\log_3 y = \log_3(9) + \log_3(x - 2)$

Combine the logarithms:

$\log_3 y = \log_3[9(x - 2)]$

Since the bases are the same, we can equate the arguments:

$y = 9(x - 2)$

Step 4: Substitute $y$ from Step 2 into the equation from Step 3

$\frac{1 + 3x}{4} = 9(x - 2)$

Step 5: Solve for $x$

Multiply both sides by 4 to clear the fraction:

$1 + 3x = 36(x - 2)$

Distribute on the right side:

$1 + 3x = 36x - 72$

Combine like terms:

$1 + 72 = 36x - 3x$

$73 = 33x$

$x = \frac{73}{33}$

Step 6: Solve for $y$

Using the value of $x$:

$y = \frac{1 + 3x}{4}$

$y = \frac{1 + 3 \left(\frac{73}{33}\right)}{4}$

$y = \frac{1 + \frac{219}{33}}{4}$

$y = \frac{\frac{33}{33} + \frac{219}{33}}{4}$

$y = \frac{\frac{252}{33}}{4}$

$y = \frac{252}{132}$

$y = \frac{21}{11}$

Final Values:

$x = \frac{73}{33} \approx 2.21$ $y = \frac{21}{11} \approx 1.91$
