Solve {l}{3A=40,8Omega-U_{2}0,3Omega}{2A=U_{1}0,3Omega-U_{2}1,3Omega}

$$\left. \begin{array} { l } { 3 A = 40,8 \Omega - U _ { 2 } 0,3 \Omega } \\ { 2 A = U _ { 1 } 0,3 \Omega - U _ { 2 } 1,3 \Omega } \end{array} \right.$$

Solve for A, Ω, U_2, U_1

$$A=\frac{68\Omega }{5}\text{, }\Omega \in \mathrm{R}\text{, }U_{2}=0\text{, }U_{1}=\frac{272}{3}\approx 90,666666667$$

$$A=0\text{, }\Omega =0\text{, }U_{2}\in \mathrm{R}\text{, }U_{1}=\frac{272}{3}\approx 90,666666667$$

$$A=0\text{, }\Omega =0\text{, }U_{2}\in \mathrm{R}\text{, }U_{1}\in \mathrm{R}\setminus \frac{272}{3};\frac{1768}{3}$$

$$A=-\frac{\Omega \left(U_{2}-136\right)}{10}\text{, }\Omega \in \mathrm{R}\text{, }U_{2}\in \mathrm{R}\setminus 136;0\text{, }U_{1}=\frac{11U_{2}+272}{3}$$

$$A=0\text{, }\Omega =0\text{, }U_{2}\in \mathrm{R}\text{, }U_{1}=\frac{1768}{3}\approx 589,333333333$$

$$A=0\text{, }\Omega \in \mathrm{R}\text{, }U_{2}=136\text{, }U_{1}=\frac{1768}{3}\approx 589,333333333$$
