### Question No. 3 #### i. Solve the following system of linear equations and find the values of \( u \), \( v \), \( w \) by Gaussian elimination method. 1. \( u + v + w = 7 \) 2. \( u - v + 2w = 9 \) 3. \( 2u + v - w = 1 \) #### ii. By expressing the following equations in matrix form and finding an inverse matrix, find the values of \( x \), \( y \), and \( z \). 1. \( 4x + y + 3z = 15 \) 2. \( 2x - z + 4z = 12 \) 3. \( y + 5z = 17 \)
