Use MATlab to solve this please and show code script

4. Solve the above set of equations symbolically by "solve" command. Follow below, study how it works. (Copy/paste in an m-file and run; otherwise, you have to retype the whole thing if there is a mistake.) syms x y z % Define symbols X, Y, Z. eql = x + 2y + 4*z == 20.5 % Move all arguments to one side: so that eql = 0 % Do the same for the other two equations. [xx, yy, zz] = solve (eql, eq2, eq3,x,y,z). % Solve equations symbolically % Note order of variable names. % The answers are rational numbers (long fractions) convert to double precision: xx = double (xx) % Repeat for yy, zz
