Thank you for your time.

Let's see

Strategy I checking currents flow at node a make sense:

i1 = 1.33/5 = 0.266
i2 = (1.33-3)/1 = -1.67
i3 = (1.33-4*1.08)/5 = -0.598

Does that make sense?

Note: I plugged your final numbers, I might have misinterpreted what your numbers represent but just wanted to show how you verify your solution.
Strategy II checking if voltages make sense:
If the voltage at node a is vA
and does v0 same as you would get if you apply voltage divider on the most left branch?
