Given:%287x%2F8%29-+%284%29=+x
Combine similar terms (remember to change sign):
-4=x-%287%2F8%29x}, Get LCD to subtract
-4=%288x-7x%29%2F8, cross multiply
-4%2A8=8x-7x
highlight%28-32=x%29, Answer
Check by going back to the given:
%287%2F8%29%28-32%29-4=-32
%287%2Fcross%288%291%29%28cross%28-32%294%29-4=-32
-28-4=-32
-32=-32, good!
Thank you,
