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.
