Mesh analysis

calculate the meshes in both problems, or see if I did right then solve for all the currents and show me step by step how to solve for the currents. I would also like to have everything set up into its matricies where all the resistances are grouped on the left then the V's in the middle and then the currents on the right.

Mesh

Solve for each loop and solve for I's, etc. As instructions say put in matrix form. Show all steps and skip no steps. I assume matrix format is all resistances on the left grouped, then V's grouped down the middle then I's on right where from left to right (Rs)*(Vs)=(Is).

Superposition principle

Souce conversions/superposition

Do all problems and show all answers and step by step how to solve skipping no steps.
