first you distribute. so, 2(x - 5) = - 11
so since you distributed it would be, 2x - 10 = -11
then you add 10 to both sides, so now its 2x=-1
now we divide,

=

so now you get : x = -0.5
-------------------------------------------------------
Lets check.
2(-0.5 - 5) = -11
so first we distribute,
-1 - 10 = -11
does -1 - 10 = -11?? Yup!! So
x= -0.5 is your answer, i hope i helped! :D
