Let $u\left(x\right)$ and $v\left(x\right)$ be differentiable functions such that $\frac{u\left(x\right)}{v\left(x\right)}=7$. If $\frac{u^{\text{'}}\left(x\right)}{v^{\text{'}}\left(x\right)}=p$ and ${\left(\frac{u\left(x\right)}{v\left(x\right)}\right)}^{\text{'}}=q$, then $\frac{p+q}{p-q}$ has a value equal to:
