i want code for it

Since this is a homework assignment, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance. [If it's not homework, just solve the system using the \ operator.]

If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the MATLAB Onramp tutorial (https://www.mathworks.com/support/learn-with-matlab-tutorials.html) to quickly learn the essentials of MATLAB.

If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.

Original question:

Solve the system of equations using Cramer's Rule x+y+z=9,2x+5y+7z=52,.2x+y-z=0.

i want code for it

And the outline:

Did you read the algorithm description on the link I posted? The elements are as follows according to this link using the notation from the link:

Where is the matrix formed by replacing the i'th column of A by the column vector b.

You simply need to write a for-loop for this to calculate each according to the above. So your loop would look like this:

for i=1:_____

Ai = _____

x(i) = _____

end

You need to fill in the blanks.
