Explain how to construct an equation that has 7 solutions

Ok, one equation with one unknown such as 'x' has only one solution, generally.

e.g.. 4x = 8

x = 2 or (x-2) = 0 [one solution]

One equation with one unknown such as '' has two solutions generally, but can have only one, or none at all.

e.g..

x = 1, x = 2 or (x-1) = 0, (x-2) = 0 [two solutions]

Can you guess your answer now?
