Node Voltage analysis- electrical engineering

Ultimately, I am trying to find power dissipated by each resistor.

I already applied node voltage analysis to the circuit.

The picture shows the diagram of the problem and my attempted solution/ equations I came up with. In the diagram, I labeled the nodes and reference node. All else was given in the diagram.

Please let me know what the next step is in order to find power dissipated by each resistor,
or if my equations for node voltage are not correct.

Thank you in advance.

If you have the potential over each resistor there is a very simply relationship that determines the power.

can you explain please?
i know that power P= current(I) x Voltage (V)

which v and I should i use?

Try combine the power equation you gave last with Ohm's law.
