I have attached a screenshot of the question I am referring to.
I was doing the above paper and I got this question wrong because I did not arrive at both values.
I can't understand why the other value (x = 2.617) works? I can arrive both the values in the mark scheme (x = 0.524 / 2.617) but I don't understand why the value x = 2.617 works? The two x values only share the same absolute y value?
Any help is much appreciated!
