The circuit diagram shows a two loop multiloop circuit. The values of the resistors and the voltage sources are listed in the circuit diagram.

$($a$)(1$ point$)$ Write down the Kirchoff equations for the circuit.

$($b$)(1$ point$)$ The current in the $R_3$ resistor is $1\mathrm{.}421$ A and is shown by the arrow in the circuit, what are the other two currents?

$($c$)(1$ point$)$ What is the voltage at labeled point $3$ relative to ground?

$1,421=I_2$
