6-9/x = x When x=1 --> 6-9 = -3 When x=2 --> 6-4.5 = 1.5 When x=3 --> 6-3 = 3 When x=4 --> 6-9/4 not equal to 4 and same is the case for any other value for x henceforth So x has only one possible value 3. Other way to solve: Algebrically, this will be of form (x-a)(x-b) = x$$^2$$ -ax -bx +ab From t...
