E1 - I1R1 - I1R2 - E2 + I2R2 = 0
E2 - I2R2 - I2R3 - I2R4 + I1R2 = 0
E1 - I1R1 - I1R2 - E2 + I2R2 = 0
E2 - I2R2 - I2R3 - I2R4 + I1R2 = 0
I bet that it's due tomorrow. You know what E2 is; so, plug that into the first equation and collect terms.

What is the question?

Read or re-read the sections on Ohm's law, nodal and mesh analysis.
Hint: matrix operations and gauss-jordan elimination will eliminate a lot of the messy algebra. It should also be possible to write the matrix equations from circuit inspection.
I notice several common terms. Try Eliminating E2 in eq'n 1 ?

wow, need help for that? wait until your course gets difficult :)

Honestly, though, I wish I had understood matrix operations when I took circuits classes as it would have simplified things greatly. If I had, I could have probably walked away with an A or B instead of a passing C. It isn't that I didn't understand the circuit theory, there was so much damned algebra in the test questions that it took forever to crank through it otherwise.
matrix reduction doesn't reduce the amount of arithmetic needed, it only translates the problem into a more abstract form.
