2^{x+1} . 3^y=144 3^{x+2} . 2^y = 27 x+y=?

We are given the system of equations:

\[
2^{x+1} \cdot 3^y = 144 \quad \text{(1)}
\]
\[
3^{x+2} \cdot 2^y = 27 \quad \text{(2)}
\]

### Step 1: Factorize the constants
Let's factorize 144 and 27 to express them in terms of powers of 2 and 3:

\[
144 = 2^4 \cdot 3^2
\]
\[
27 = 3^3
\]

Now, rewrite the system of equations:

\[
2^{x+1} \cdot 3^y = 2^4 \cdot 3^2 \quad \text{(3)}
\]
\[
3^{x+2} \cdot 2^y = 3^3 \quad \text{(4)}
\]

### Step 2: Compare powers of 2 and 3
#### From Equation (3):
Equating powers of 2 and powers of 3 on both sides, we get:

For powers of 2:
\[
x+1 = 4 \quad \Rightarrow \quad x = 3
\]

For powers of 3:
\[
y = 2
\]

#### From Equation (4):
Substitute \(x = 3\) and \(y = 2\) into the second equation:

\[
3^{3+2} \cdot 2^2 = 3^3
\]
This simplifies to:
\[
3^5 \cdot 2^2 = 3^3
\]
This equation does not hold. I made an algebraic mistake here. Let's go back and rethink the approach.

#### New Approach:

The exact solution for \( x \) and \( y \) involves logarithmic expressions, but to find simpler numeric values, it would be best to approximate them. Let me simplify and provide the values numerically.It seems like I can’t do more advanced data analysis right now. Please try again later. However, if you'd like, I can walk you through solving this step by step manually or explain the logarithmic expressions further.
