x^2*y-z=1.5
x-3y^0.5+xz=-2
x+y-z=4.2

You can use "solve" to find solutions for systems of equations. For example,
>> syms x y
>> [x_ans, y_ans] = solve(x + y == 9, y-x == 1)
x_ans =
4
y_ans =
5
The documentation offers more detail on the function, as well as several useful links for approaching equations solving, e.g.:
