Final answer:
Without a circuit diagram or complete nodal equations, we cannot provide a detailed step-by-step solution for finding Vx or the power 'delivered' by the current sources using nodal analysis. The calculation for power delivered follows the formula P = IV, which requires information about the current supplied and the voltage at the relevant nodes.
Step-by-step explanation:
In nodal analysis, we are tasked with finding the voltage at a particular node in a circuit (in this case, Vx) by using Kirchhoff's laws and the concept of equivalent nodes. Unfortunately, without a circuit diagram or full nodal equations, we cannot provide a step-by-step solution for Vx. However, we can generalize the approach to the problem: to find Vx, one would write down the nodal equations based on the circuit configuration and solve the system of linear equations to find the node voltages.
The power 'delivered' by current sources can be found using the formula P = IV, where P is power in watts, I is the current in amperes, and V is the voltage across the current source. By knowing the current supplied by each source and the voltage at the nodes it connects, this calculation can be completed. Unfortunately, the specifics of the current sources and circuit are not provided, so an exact numerical answer cannot be given.
If numerical values and a circuit diagram were provided, a clear step-by-step process could be offered, and we would be able to determine the correct values for Vx and the power delivered.
