How do I solve this one

just olya [345]

6/7Y - 18/28 =-15/14
First, let's get a common denominator
24/28Y - 18/28 =-30/28
Move your terms to isolate Y
24/28Y=-12/28
Multiply by 28 on both sides
24/Y=-12
Times both sides by Y, then divide by -12
24/-12=Y
Simplify
-2=Y

I hope this Helps!

The Epson workforce G7-1500 takes twice the time required by the Epson Workforce Pro GT-S50 to scan the manuscript for a book. I

neonofarm [45]

Let t be the time in minutes for the GT-S50 to scan the manuscript, working alone.
Then the G7-1500 will take 2t minutes to scan the manuscript, working alone.
If both machines work together for 1 minute they will scan 1/5 of the manuscript.
$\frac{1}{t} + \frac{1}{2t} = \frac{1}{5}$
$\frac{3}{2t} = \frac{1}{5}$
2t = 15
t = 7.5
When working alone, the machines will take the following times to scan the manuscript:
G7-1500: 15 minutes, GT-S50: 7.5 minutes.
