System of 9 linear equations, 9 variables

Which is the solution (if any) of the following system of equations:

10/3a+b=10/3
a*x+b=2x+10
c*x+d=2x+10
10c+d=0
-2e+f=6
e*y+f=0
a*y+b=0
e*z+f=-2z+10
c*z+d=-2z+10

The system is not linear, since it has terms which are the product of two unknowns. You could eliminate x,y,z and get six equations involving a,b,c,d,e,f, but going further would require solving nonlinear equations.
