  This paper examines the behavior of a positive solution $u\in
C^{1,\alpha}(\Bar{\Omega})$ of the $(p,q)$ Laplace equation with a singular
term and zero Dirichlet boundary condition. Specifically, we consider the
equation: \begin{equation*} -div(|\nabla u|^{p-2}\nabla u+ a(x) |\nabla
u|^{q-2}\nabla u) &= \frac{g(x)}{u^\delta}+h(x)f(u) \, &\text{in} \thinspace
B_R(x_0), \quad u & =0 \ &\text{on} \ \partial B_R(x_0). \end{equation*} We
assume that $0<\delta<1$, $1<p\leq q<\infty$, and $f$ is a $C^1(\mathbb{R})$
nondecreasing function. Our analysis uses the moving plane method to
investigate the symmetry and monotonicity properties of $u$. Additionally, we
establish a strong comparison principle for solutions of the $(p,q)$ Laplace
equation with radial symmetry under the assumptions that $1<p\leq q\leq 2$ and
$f\equiv1$.
