$-\dfrac{190}{63}x$

Step-by-step explanation:

You are adding two like terms which are fractions with denominators 9 and 7.

You need a common denominator. The LCD of 9 and 7 is 63.

$-\dfrac{31}{9}x + \dfrac{3}{7}x = -\dfrac{31}{9} \times \dfrac{7}{7}x + \dfrac{3}{7} \times \dfrac{9}{9}x = -\dfrac{217}{63}x + \dfrac{27}{63}x = -\dfrac{190}{63}x$
