    Step-by-step explanation:

    7/10=r - (-8/5)

    7/10=r+8/5

    7/10 - 8/5 = r + 8/5 - 8/5

    7/10 - 8/5 = r

    7/10 - 16/10 = r

    -9/10 = r

    r = - 0.9

    -9/10 = r

    Step-by-step explanation:

    7/10=r - (-8/5)

    Subtracting a negative is like adding

    7/10=r + (8/5)

    Subtract 8/5 from each side

    7/10 - 8/5=r + (8/5) - 8/5

    7/10 - 8/5 = r

    Get a common denominator

    7/10 - 16/10 = r

    -9/10 = r
