(a) Formulate mesh-current equations for the circuit in Figure \(\mathrm{P}_{3}-15\).
(b) Use MATLAB to find symbolic expressions for \(v_{\mathrm{x}}\) and \(i\) \(x\) in terms of the parameters in the circuit.
(c) Find numeric values for \(v_{\mathrm{x}}\) and \(i_{\mathrm{x}}\) when \(R_{1}=R_{2}=8.2\)
\(\mathrm{k} \Omega, R_{3}=22 \mathrm{k} \Omega, R_{4}=33 \mathrm{k} \Omega, i_{\mathrm{S}}=2.5 \mathrm{~mA}, v_{\mathrm{S} 1}=15 \mathrm{~V}\), and \(v\) \(\mathrm{S} 2=5 \mathrm{~V}\).
(d) Find the power supplied by
(e) Use Multisim to verify your solutions to parts (c) and (d) are correct.
