What ways have you tried?
Did you go too far?
Possibly. But the OP didn't seem to have sufficient grounding in nodal analysis to be able to know what to do with cryptic hints.
The OP seemed to need an example to demonstrate that nodal analysis was possible and even the best way to analyse this circuit. Perhaps I should have constructed the example with slightly different component values in order to demonstrate the method without providing the exact solution. I'll do that next time.
The OP posted this on at least 2 other forums, and got a solution on one of them right away.
And IMO that is sad, a bunch of inept graduates with degrees that they obtained by cheating due to Internet do-gooders that willingly did their homework for them...
The equations for nodal analysis are the easiest to write, and least likely to make mistakes. Using a symbolic algebra program allows for a minimum busy work solution. See attached analysis.
The node equations are written for each of the identified nodes: V1, V2, V3, & V4 with currents I1 & I2. I like the convention that current leaving a node is positive while current entering a node is considered negative. That way the equation for any node always begins (V,node - V,othernode). Note that here V1=100 and I1 is a multiple of (V1-V2)/6 so there are 4 equations and 4 unknowns (V2,V3,V4,I2). Once the initial equations are written, MathCAD makes it easy to solve the system of 4 equations by repeated copying and pasting of substitutions. Algebra manipulations are handled automatically by the 'solve' command. Calculations are done in place and intermediate results are not shown, otherwise the size of the pdf file would exceed the limit for posting here.
Thanks. There must be an efficient method for solving this though.

You did originally before you edited the post, with some excuse about how you just whipped up this problem for the heck of it... You must have realized how silly that sounded since it's been pointed out you cross posted the thread to multiple forms seeking an answer rather than actually interacting to discover and discuss said answer and how to go about solving it

Hahahahaha
.....actually this was a practice problem that I was trying to do but didn't know where to start. I've solved a number circuits using nodal analysis,mesh analysis and KVL/KCL on networks with fewer elements but that became boring so I decided to try some hard ones and....
On that note I usually do all my work and rarely ask for help except for when I attempt to move from a basic or intermediate understanding of something to an advanced understanding.
