question 7 and part a, b, c please

7. We now have three relations and three unknowns. So we should be able to determine the unknown currents. To do so follow the steps below: . Don't change the sign of you get a negative current until all calculations are finished. The relations were established assuming your guess for the current direction. Changing the sign before you finish will make the other relations invalid. a. Start with the simplest equation and solve for one of the unknown currents in terms of the other two. Substitute this into the two remaining equations. You should now have two relations and two unknowns. Repeat the process for the two relations and two unknowns. b. You should now have one relation and one unknown. Solve for the unknown current and then substitute back in to solve for the other two currents. C.
