  • oh cake

    it does not equal -3.9 because you have to get rid of the - in the y

    so what you do is divide both sides by -1 because there is no other number in front of the y

    so a - divided by a - would be a +

    so therefore it is 3.9

    ;)

  • no u would have to divide both sides of the equation by -1 so the -y becomes a +y so it wud b +3.9

  • y equals 3.9.

    Change y to a positive and change what equals y to a positive.

    I am in Algebra 2.

    Easy.

  • no.

    if you divide both sides out by -1

    y= 3.9

  • No; if you multiply both sides by negative one: -1 * -y = -3.9 * -1

    you will get: y = 3.9
