#w=1#

Explanation:

1) start off writing #11w + 2(3w - 1) = 15w#
2) distribute the #2# to the #(3w - 1)#
-you then get #6w - 2# because #2(3) = 6 and 2(-1) = -1#
3) now write #11w+6w-2=15w#
4) add #11w and 6w # to get #17w#
5) now you have #17w-2=15w#
6) subtract #17w# from both sides to get #w# on its own side
7) you now have #-2=-2w#
8) divide each side by #-2# to get #w# by itself

work:

#11w+2(3w-1)=15w#
#11w+6w-2=15w#
#17w-2=15w#
#-2=-2w#
#1=w#

to check, plug in #1# for #w#

#11(1)+2(3(1)-1)=15(1)#
#11+2(3-1)=15#
#11+2(2)=15#
#11+4=15#
#15=15#
