using multiplication principle -2/5y=-14/15

  • algebra - ,

    Is the y in the denominator?
    When typing algebra, you need to distinguish between things like -2/(5y) and -(2/5)*y

    Parentheses can help you do that.

    If you mean
    -(2/5)y=-14/15
    multiply both sides by -5/2.

    y = 70/30 = 7/3
