What is the value of the rational expression the fraction with numerator 6 minus x and denominator x plus 5 when x is equal to 2 ?

Substitute x = 2 into the expression (6 − x)/(x + 5). The numerator becomes 6 − 2 = 4, and the denominator becomes 2 + 5 = 7, so the value is 4/7. This matches choice A, four sevenths.
