Solucionar T=a*m_{a}=b*m_{b}

$$T = a \cdot m _ { a } = b \cdot m _ { b }$$

Calcular (solución compleja)

$$T=am_{a}\text{ and }am_{a}=bm_{b}$$

Resolver para m_b

$$\left\{\begin{matrix}m_{b}=\frac{am_{a}}{b}\text{, }&T=am_{a}\text{ and }b\neq 0\\m_{b}\in \mathrm{R}\text{, }&\left(m_{a}=0\text{ or }a=0\right)\text{ and }T=0\text{ and }b=0\end{matrix}\right,$$

Resolver para m_a

$$\left\{\begin{matrix}m_{a}=\frac{bm_{b}}{a}\text{, }&T=bm_{b}\text{ and }a\neq 0\\m_{a}\in \mathrm{R}\text{, }&\left(m_{b}=0\text{ or }b=0\right)\text{ and }T=0\text{ and }a=0\end{matrix}\right,$$
