Solve Constant from A System of Equations

I don't seem to understand how solving multiple equations in CAS works. I need to determine a constant so that two curves overlap by solving this system of equations:

12x = a

-6x^2 + ax - a/4 = 0

There should be two solutions; x = 1/2, a = 6 or x = 0, a = 0, but I can't figure out how to get multiple solutions for multiple variables in CAS. I've tried Solve and Solutions commands but it shows me the answers like in the picture.

You need to type

a*x

not

ax

Thanks, didn't realize the problem was in the syntax
