1. The problem statement, all variables and given/known data

Hi, this is my first time posting so if there is any advice on how to make this post cleaner, please tell me! I've been stuck on a problem and I can't figure out what I'm doing wrong. I have attached the problem and the attempt at solving the problem below. I am supposed to find E1 using nodal analysis.

2. Relevant equations
In my work that I attached, I replaced the name E1 with node A. I also used a supernode between A and C.

3. The attempt at a solution
1. The problem statement, all variables and given/known data
I solved Va = 10/4, however the solution that my professor gave me says its supposed to be 42/3. Any help is appreciated!
