syms x y P Q
eqns = [(((x-Xc(4)).^2) + ((y-Yc(4)).^2)== R^2), (P^2 + Q^2 == R^2)]
S = solve(eqns, [x y P Q])
S =
[ empty sym ]
how it solve??

What are your values for Xc(4) and Yc(4) and R ?
Which version are you using?
You are trying to solve two equations in four unknowns; there are an infinite number of solutions.

Xc(4) = 0.9304, Yc(4) = 0.9304 2014 version R = 25 modifying given equations as follows syms x y N1 = ((x-Xc(4)).^2) + ((y-Yc(4)).^2)== (R^2) N2 = (x^2 + y^2 == R^2) PX = solve(N1) PY = solve(N2)
i have to get the value of x and y
