Rewrite the linear system by using the matrix formalism Ax = b (you can define A and b in the usual way). Then use the operator \ to compute the solution

This sounds like a homework assignment. If it is, 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 you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the free 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.

Hi Khandaker, from your question I understand you want to solve a system of linear equations.
Firstly declare the system of equations.
syms x y z
eqn1 = 2*x + y + 5*z == 10;
eqn2 = 4*x + 2*y + 5*z == 16;
eqn3 = 3*x + 3*y + 8*z == 7;
Now solve the system of equations using solve. The inputs to solve are a vector of equations, and a vector of variables to solve the equations for.
sol = solve([eqn1, eqn2, eqn3], [x, y, z]);
xSol = sol.x
ySol = sol.y
zSol = sol.z
