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.
