Hello,
5/z=8/z-1/2
Start with,
moving the second term on the left side,
5/z - 8/z = -1/2
Take the LCM " z"
(5-8)/z = -1/2
-3/z = -1/2
cancel the both negative signs,
3/z = 1/2
Cross multiply the terms,
3*2 = 1*z
6 = z
So,
z = 6
Hope u got your answer.
THank you!

Multiply thru by 2z
10 = 16 - z
z = 6

+5%2Fz+=+8%2Fz+-+1%2F2+
.
Subtract 8/z from both sides.
.
+-3%2Fz+=+-1%2F2+
.
Cross multiply.
.
+-6+=+-z+
.
+z+=+6+
.
Check the answer.
.
+5%2F6+=+8%2F6+-+1%2F2+=+8%2F6+-3%2F6+=+5%2F6+
.
Correct.
.
Answer: z = 6
.
Done.
