Solve for y,

xy + x = -3

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

  • Stumped at Algebra II - ,

    How in the world do you do this? I'm so confused. Thank you all for your time and help...

    -2 < 2x - 5 < 3

  • algebra - ,

    just 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

  • algebra - ,

    -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

    Thank you Steve for your help!
