xy + x = -3

How do you do this? I can't seem to come up with the correct answer...

**Andrea**, Wednesday, September 26, 2012 at 5:55pmHow in the world do you do this? I'm so confused. Thank you all for your time and help...

-2 < 2x - 5 < 3

**Steve**, Wednesday, September 26, 2012 at 5:56pmjust isolate all the y terms on te left:

xy = -3-x

now divide by x:

y = (-3-x)/x = -3/x - 1

as long as x≠0

**Steve**, Wednesday, September 26, 2012 at 5:59pm-2 < 2x - 5 < 3

add 5 to all parts:

-3+5 = 2x-5+5 < 3+5

2 < 2x < 8

now divide by 2:

1 < x < 4

These are not always so simple. You might have to separate into two problems to be solved separately:

-2 < 2x-5 and 2x-5 < 3
