Question

Please help!!! (-x/2)+(1/2x)=(-4/x)

Answer 1

Are you solving this for x? You can't because the left side is eliminated by subtracting (1/2)x from (1/2)x. That leaves nothing on the left.
`0= (-4)/(x)`
you can't solve that for x because when you multiply both sides by x, 0*x = 0 and
`0 \\eq 4`
I think you made a mistake in your typing or something...unless the answer was no solution!
