I am trying to use 'solve' to solve this system of equations:

`solve('5*x+6*y=5','10*x+12*y=10')`

and I get the a return saying:

`Warning: The solutions are parametrized by the symbols:z = C_`

and when I try to look at the solutions it introduces the variable z :

`soln =[ 1 - (6*z)/5, z]`

How can I fix this?
