Question

7/2x+1/2x = 18+ 9/2x

Answer 1

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

$4x=18+\frac{9}{2} x$

-9/2x       -9/2x

$-\frac{1}{2} x=18$   because if you do 8/2-9/2 it's -1/2

then multiply the reciprocal to both sides so

$(\frac{2}{-1})(-\frac{1}{2}x)=(\frac{2}{-1})(18)$

which then cancels out -1/2 and makes it

x=-36
