If the discriminant of a quadratic equation is less then 0 then it will have no real solutions.

240 is not an equation and so the concept of solutions is meaningless.

A single linear equation in two variables has infinitely many solutions. Two linear equations in two variables will usually have a single solution - but it is also possible that they have no solution, or infinitely many solutions.

0 = 0 is an identity and not an equation. Equations have solutions, identities do not.

Equations can have many solutions. The equation of a straight line, for example, defines all points on the line. Even a simple equation such as x+y=5 can have a variety of solutions (x=1 when y=4, x=2 when y=3 and so on)
