    M+5=-7.3

    m needs to be lone

    move 5 to the other side of = sign dont forget to change sign

    m=-7.3-5

    no when two signs are the same we add

    so its like saying

    m=-7.3 + (-5)

    m=-12.3 now lets check it

    -12.3 = + 5=-7.3

    -12.3=-5 + (-7.3)

    -12.3=-12.3 so we did it right

    so your answer would be m=-7.3-5

    It's A. m = - 7.3 - 5.

    You can always check it ...

    -7.3 - 5 = - 12.3

    -12.3 + 5 = - 7.3
