#color(magenta)("x=17")#

Explanation:

#color(blue)("Add 6 to both sides of the equation. This will allow you to")# #color(blue)("get the variable (a letter that takes the place of an unknown"# #color(blue)("number) and the constant (a number) by themselves so you can solve for x:")#

#xcancel-6=11#
#color(white)(aa)cancel+6 +6#

Now, on the left side you are just left with #x# since (-6)+6 = 0. On the right side you end up with 17 because 11+6 = 17.

Thus,

#color(blue)("x=17#
