Answer:
x=-36
Step-by-step explanation:
Add the 7/2x +1/2x to be 8/2x which means that it'll be 4x=18=9/2
then subtract 9/2x on both sides so itll be
[tex]4x=18+\frac{9}{2} x[/tex]
-9/2x -9/2x
[tex]-\frac{1}{2} x=18[/tex] because if you do 8/2-9/2 it's -1/2
then multiply the reciprocal to both sides so
[tex](\frac{2}{-1})(-\frac{1}{2}x)=(\frac{2}{-1})(18)[/tex]
which then cancels out -1/2 and makes it
x=-36
