Your Brother’s Name
Brother's Address
Dear Brother,
I am thrilled to inform you that I have recently completed the construction of my new home in the serene hills of Uttarakhand. It would mean so much to me if you and your family could spend a few days with us and enjoy the tranquility of the mountains. The house is located in a beautiful spot with breathtaking views of the valley. I have planned some exciting activities for your visit, including trekking, sightseeing, and relaxing amidst nature. Please let me know a suitable time for your visit. I look forward to hosting you all.
Warm regards,
Srikanth Sharma
If \[ A = \begin{bmatrix} 1 & 2 & 0 \\ -2 & -1 & -2 \\ 0 & -1 & 1 \end{bmatrix} \] then find \( A^{-1} \). Hence, solve the system of linear equations: \[ x - 2y = 10, \] \[ 2x - y - z = 8, \] \[ -2y + z = 7. \]
