Question 503868: y-9/y+5=1/7 help solve
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! (y-9)/(y+5) = 1/7
---
Cross-multiply to get:
7(y-9) = y+5
7y-63 = y+5
6y = 68
y = 11 1/3
==============
Check:
((34/3)-9)/((34/3)+5) = 1/7
-----
((34/3)-(27/3))/((34/3)+(15/3)] = 1/7
----
(7/3)/(49/3) = 1/7
---
7/49 = 1/7
----
1/7 = 1/7
