Question 884182
Those not equivalent.  You most likely mean to show  {{{highlight_green((8x-7)/3=11)}}}.


Multiply both sides by  3:

{{{8x-7=3*11}}}

ADD 7 to both sides:

{{{8x=3*11+7}}}

Multiply both sides by {{{1/8}}}:

{{{x=(3*11+7)/8}}}


Simplify, computing the finished value for x.


Note that I saved all the computing for last.
