Please show what have you tried yet.
If you need help to begin with, check out the LU matrix factorization documentation - lu

I understand that you wanted to determine the variable x using LU decomposition method.
Please refer to the below code snippet for the same
A = [-1 1 2; 1 2 -1; -2 -2 2]
c = [7;2;0]
[L,U] = lu(A)
%In LU Decomposition, LUX = c
D = L*U
x = (D)\c
Please refer to the following documentation link for more information on LU decomposition
