please can you solve it manually

Problem \#1 Solve x1+x2x3=36x1+2x2+2x3=23x1+4x2+x3=1 with a) Nave Gaussian elimination method. b) Gaussian elimination method with scaled partial pivoting. Show the scale vector, the ratio and the index vectors in each step. c) Find the determinant of the original system from the system you obtained in the last step of part b. Problem \#2 Given the system of equations A=112461112b=7135 a) By evaluating the determinant, classify the A matrix as singular, ill-conditioned or well conditioned. b) Solve Ax=b using the Gauss-Jordan Technique
