how to solve for y for this question,

y = (x+2)/(x-3).

and

AR-X, is it a meta or ortho/para director?

one of the question in the ADA sample test said it is para not meta, why?
Halogens are ring DEACTIVATORS that are Ortho/Para directors. Read any organic chemistry textbook and they will clearly explain why this is the case.

how to solve for y for this question,

y = (x+2)/(x-3).
Cross-Multiply:

xy - 3y = x + 2

Bring all the terms with x to one side:

xy - x = 2 + 3y

Factor out x:

x(y - 1) = 2 + 3y

x = (2+3y)/(y-1)

and

AR-X, is it a meta or ortho/para director?

one of the question in the ADA sample test said it is para not meta, why?
Hope this helps!
