Hi, at first you have to declare x, y and z as symbolic variables:
syms x y z;
Then you can use the function solve():
result = solve(x*y==5, x*z == 15, y+z==1, [x y z]);
You can then access the results via result.x, result.y and result.z . Next time you could use Google, I found the solution in less than a minute: http://www.mathworks.com/matlabcentral/answers/248493-how-to-solve-implicit-symbolic-equations-using-mupad
Kind regards, Stefan
