can someone explain and answer this equation for me. 7y - 6 < 6y -1 Thanks

  • algebra -

    subtract 6y from each side
    y-6<-1
    add 6 to each side
    y<5

  • algebra -

    7y - 6 < 6y -1
    7y - 6y < -1 + 6
    y < 5

    notice I performed the same steps as I would for an ordinary equation.
    The only exception is, ...
    "When you multiply or divide both sides by a negative, the inequality sign has to be reversed"

    e.g.

    if you had
    -3x > 12
    then
    x < -4 , ( I divided both sides by -3 )
