    You have to show some effort first before you'll get help.

    Do KCL at nodes V2 and V4 and V5 then notice that V3=V5, and that you know V1 = 24V, so you need 3 sets of linear equations. Mess around with algebra, stick it in a 3X3 matrix and you're done. But we expect you to do the work yourself.

    Btw, Just did it myself by hand to prove to myself that I can still do these type of things. Current i should end up being 1.75A, which the circuit simulator confirms.

    I love the values professors in beginning courses give. 1.75A would cause your circuit to catch on fire in real life.

    Perhaps it would be beneficial to take a look at the node voltage method applied to the solution of an example problem such as the one located here in the AAC ebook.
