(a) Formulate mesh-current equations for the circuit in Figure P3-14 . ( Hint: Use a supermesh.)
(b) Reduce the circuit to one node using source transformations and solve for the node voltage \(v_{\mathrm{A}}\).
(c) Solve for \(v_{\mathrm{x}}\) and \(i_{\mathrm{x}}\) when \(R_{1}=2.7 \mathrm{k} \Omega, R_{2}=1.5 \mathrm{k} \Omega, R_{3}\)
\(=680 \Omega, R_{4}=2.2 \mathrm{k} \Omega, i_{\mathrm{S}}=10 \mathrm{~mA}, v_{\mathrm{S} 1}=5 \mathrm{~V}\), and \(v_{\mathrm{S} 2}=\) \(10 \mathrm{~V}\).
(d) Use Multisim to verify your results in part (c).
