![### Linear Transformation in \(\mathbb{R}^2\)
#### Problem Statement
Let \( T: \mathbb{R}^2 \rightarrow \mathbb{R}^2 \) be a linear transformation such that
\[ T(x_1, x_2) = (x_1 + x_2, 2x_1 + 6x_2). \]
Find \( \mathbf{x} \) such that
\[ T(\mathbf{x}) = (5, -6). \]
*Solution:*
\[ \mathbf{x} = (9, -4). \]
---
### Explanation:
To find the vector \(\mathbf{x} = (x_1, x_2)\) such that \(T(\mathbf{x}) = (5, -6)\), we start by writing down the transformation equations:
\[
T(x_1, x_2) = (x_1 + x_2, 2x_1 + 6x_2).
\]
We need to find \(x_1\) and \(x_2\) such that:
\[
x_1 + x_2 = 5
\]
\[
2x_1 + 6x_2 = -6.
\]
Solve these equations simultaneously:
1. \(x_1 + x_2 = 5\)
2. \(2x_1 + 6x_2 = -6\)
From the first equation:
\[
x_1 = 5 - x_2.
\]
Substitute \(x_1\) in the second equation:
\[
2(5 - x_2) + 6x_2 = -6.
\]
Simplify:
\[
10 - 2x_2 + 6x_2 = -6,
\]
\[
10 + 4x_2 = -6,
\]
\[
4x_2 = -6 - 10,
\]
\[
4x_2 = -16,
\]
\[
x_2 = -4.
\]
Substitute \(x_2 = -4\) back into the first equation:
\[
x_1 = 5 - (-4),
\]
\[
x_1 = 9.
\]
So, \(\mathbf{x} = (9, -4)\).
### Conclusion
Thus, the vector \](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8b6c3689-2b60-4c25-801e-fccc9acdd031%2Fd6d8623e-c81c-4a86-99a4-4ebf9d735142%2Fucn27se_processed.png&w=3840&q=75)
