Can someone help me solve this using exel. 

Thanks 

Ohm's Law, Kirchoff's Voltage Law, and Kirchoff's Current Law (shown below for your reference) are used to generate a system of three equations that describe the operation of the circuit shown below. Use matrix array functions in Excel to find the currents i₁, 12, and i3. The voltage supply and resistance values are listed in the accompanying table. Ohm's Law. V = IR Kirchoff's Voltage Law. For a closed circuit (loop), the algebraic sum of all changes in voltage must be zero, i.e., E-R₁i₁ - R₂i2 = 0, and E-R₁i1 - R3i3 = 0; Kirchoff's Current Law. At any junction in a circuit, the input current(s) must equal the output current(s), i.e., 1₁-1₂-13 = 0 The corresponding system of equations is: a) Display your coefficient matrix and your constant matrix. b) Display the determinant of the coefficient matrix to see if it's possible to find an inverse. Find the inverse of the coefficient matrix. c) d) Use the inverse of the coefficient matrix to determine the currents 1₁, 12, and 13.
