Solutiob;

The linear transformation;

T[x1x2x3x4]T\begin{bmatrix} x_1 \\ x_2\\ x_3\\ x_4 \end{bmatrix} =[3705]\begin{bmatrix} 3 & -7&0&5 \\ \end{bmatrix}

The Null space of the transform is the solution of the homogeneous system Ax=0;

Where A is the matrix;

[3705]\begin{bmatrix} 3 &-7&0&5\\ \end{bmatrix}

3x17x2+5x4=03x_1-7x_2+5x_4=0
