Do you have the answer?

No, the answer isn't available. The problem is from "Fundamentals of Electric Circuits" 4th edition, problem number 3.10

I calculated Io to be 1Amp, but to be honest I am pretty bad at this... Tested it in LTSpice and it seems it's most accurate at 0.95 Amps...

I applied KCL to the 3 nodes and got the value of I0= 15/17= 0.88A.
Everyone I asked this question have different answers.

Show as your work, because the correct answer is -4A

I also get the same answer as Jony's.
Here is the LTspice simulation to confirm the result:

Using nodal analysis, the correct answer is -4 A, as founded.
