Pr$3.$ Don't calculate. In the circuit below, write nodal analysis equations that we can use to solve node voltages V$1,$ V$2,$ V$3.$ Then assume you have the values of these node voltages, write the equations that can be used to solve Ix$,$ Iy$,$ the power of the current source and the voltage source in terms of V$1,$ V$2,$ V$3.$

Node voltages:

$V_1$:$\frac{V_1-V_2}{3}+\frac{V_1}{4}+6=0$

$V_2$:$\frac{V_2-V_1}{3}+\frac{V_2-V_3}{2}+\frac{V_2-48}{2}=0$

Equations used to solve Ix $,$ ly$,$ the power of the current source and the voltage source in terms of V$1,$ V$2,$ V$3.$ Don't solve
