%%Solve System of Linear Equations Using solve
%Dejen Ketema April 2019
%Example 1
% 2*x+y+z=2
% -x+y-z=3
% x+2*y+3*z=-10
% Declare the system of equations.
syms x y z
eqn1 = 2*x + y + z == 2;
eqn2 = -x + y - z == 3;
eqn3 = x + 2*y + 3*z == -10;
%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]);
x = sol.x;
y = sol.y;
z= sol.z;
st=[x y z];
