How many solutions does the equation 2x − 2 = x have?
Would it be 1

Usually an inequality equation has two solutions ...
2x2 = x
2x2 = x or 2x + 2 = x , where x ≥ 0
x = 2 or 3x = 2
x = 2 or x = 2/3
both answers check out, so there are two solutions.

(2x2) = x
x = 2
(2x2) = x
2x + 2 = x
3 x = 2
x = 2/3
