linear system of equations

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?

Your equations are not independent. The second is 2 times the first

Answer 2

parametrized by the symbols means the equation has a common parameter making them dependent on each other. So you can't solve them as simultaneous equations.
