$14+x$
Commutative properties: $a+b=b+a,\qquad ab=ba$ Associative properties:$a+(b+c)=(a+b)+c,\qquad a(bc)=(ab)c$ Distributive property: $\quad A(x+y)=Ax+Ay$ --- $3+(x+11)=\qquad$ ...commutative property: x and 11 can change places $=3+(11+x)=$ ...associative property: we can change groupings, $=(3+11)+x$ $=14+x$
