Answer:

#x=5#

Explanation:

First I would multiply both sides with #-1#:
#-(1+7x)-6(-7-x)=36#
#=>1+7x+6(-7-x)=-36#
#=>1+7x-42-6x=-36# (Multiply 6 with each term in the parenthesis.
#=>x-41+41=-36+41# (add 41 to both sides to get only the unknown to the left of the equality sign)
#0>x=5#

Last step is to use the value of #x=5# in the original equation to see if the left side equals the right side. I'll leave that to you.
