I need help with these please. Thanks

Find a vector **x** whose image under T, defined by \( T(x) = Ax \), is **b**, and determine whether **x** is unique. Let

\[
A = \begin{bmatrix} 
1 & 3 & 6 \\
4 & 15 & 27 \\
0 & 1 & 1 \\
-4 & -13 & -25 
\end{bmatrix}, \quad b = \begin{bmatrix} 
17 \\ 
80 \\ 
4 \\ 
-72 
\end{bmatrix}.
\]

If \( T \) is defined by \( T(x) = Ax \), find a vector \( x \) whose image under \( T \) is \( b \), and determine whether \( x \) is unique. Let

\[
A = \begin{bmatrix} 1 & -4 & 5 \\ 0 & 1 & -3 \\ 5 & -21 & 25 \end{bmatrix} 
\]

and 

\[
b = \begin{bmatrix} -6 \\ -25 \\ -2 \end{bmatrix}.
