y'+2y=2x

This is not a system of ODEs, it is two separate 1st order ODEs, with
two separate solutions. A system of ODEs has the same number of
independent variables as the number of 1st order ODEs. You have only
one independent variable, y.

Go back and look at where you got the equations from, your mistake is
probably there.

OK, here's the right equations;

(y'+z')+2(y+z)=2x
2(y'+z')+(y+z)=4x

Ok, now how do I solve this? Eliminate one the independant variables?
