The problem as is is not without ambiguities.
You can clarify the question by typing the expression on a single line, remembering to enclose the numerator or denominator in parentheses, and not forgetting that multiplication and division have higher precedence over addition and subtraction.
For example:
(x+1)/(2x-8) - (x+2)/(12-3x)
would not be ambiguous.
x+1 - x+2 = ?
--- ---
2x-8 12-3x
