please solve using matlab. i included the slides referenced in the problem

1. (25 Points) Gaussian Elimination. Solve the system of equations below as presented in Lecture 3 (see slides) using the following steps: 3x1+2x25x3+10x4=202x16x25x3+7x4=12x1+7x25x36x4=34x1+x27x3+6x4=28 Step 1) Create A and b Step 2) Concatenate C=[A b ] Step 3) Eliminate all coefficients in 1st column below A(1,1) Step 4) Eliminate all coefficients in 2 nd column below A(2,2) Step 5) Eliminate all coefficients in 3rd column below A(3,3) Step 5) Back substitute to solve for x4,x3,x2,&x1 Step 6) Compare your solution, x, to one you compute from MATLAB BONUS: If you provide a "for" loop based solution with limits based on dimensions of the A matrix (i.e. "for row_ctr = 2:A(size(A,1))"), then you will earn 10 additional points. Example: Gaussian elimination: Step 1 Example: Gaussian elimination: Step 2 \[ \begin{aligned} \multicolumn{1}{l}{} & x_{1}+4 x_{2}+3 x_{3} & =5 \\ \text { Eliminate } & -2 x_{2}-5 x_{3} & =-9 \\ \text { Entry } & -18 x_{2}-7 x_{3} & =-23 \end{aligned} \] Eliminate Entries >>(3)=C(3,4)/C(3,3)Howdoyoucomputex1andx2?Answerx1x2x3=2.31580.68421.5263
