please solve:

8y - 12 < 7y - 7

{ y y < ?
there is supposed to be a straight line between the y and y

  • math -

    subtract 7x from both sides
    add 12 to each side.

  • math -

    do you mean subtract 7y from both sides? There is no 7x

  • math -

    yes, 7y

  • math -

    8y-12<7y-7
    8y -12 -7y<7y-7-7y
    y-12<-7
    y-12+12<-7+12
    y<5

    Is this correct?

  • math -

    mucho correct.
