Fill in the Blank

A logistics coordinator is simplifying the rational expression 142xx249\frac{14-2x}{x^2-49} for a shipping cost formula. After factoring, the expression is written as 2(7x)(x7)(x+7)\frac{2(7-x)}{(x-7)(x+7)}. To finish the simplification, the coordinator identifies the opposite factors (7x)(7-x) and (x7)(x-7). According to the opposite factors property, the ratio 7xx7\frac{7-x}{x-7} simplifies to the numerical value of ____.
