solve these problem ASAP send me paper solution quickly writing must be clear and show the work solve all parts

Juestion 2. For the circuit in Figure 2, use KCL to compute the value of i; and is by following the steps enumerated below. Figure 2: Circuit to be used for Question 2. Define the electrical reference, i.e., ground, and label the potentials with respect to said reference. Write the nodal equations. Was a supernode equation required for your previous answer? If so, why? If not, why not? Express the set of equations and unknowns in the standard linear format. solve the matrix equation you found in your previous answer by any method. Please state your method. Use your previous result to compute i1 and is. In your words, what is the meaning of i; and i; and what do the results tell you about the direction of current through the 80 2 resistor
