    Answer:

    m = -100

    Step-by-step explanation:

    (1/5)m -12 = -32

    add 12 on both sides

    (1/5)m = -20

    multiply both sides by 5

    m = -100

    Answer:

    m = -100

    Step-by-step explanation:

    So in order to solve this equation we are going to have to convert 1/5m to a decimal, this will make it easier to solve the equation:

    1/5m = 0.2m

    Next we are going to take our 0.2m and place it within the equation where 1/5m is:

    ⅕m – 12 = -32  or 0.2m – 12 = -32

    So now we are going to add 12 to both sides of the equal sign in the equation to segregate the 0.2m within the equation:

    0.2m – 12 = -32  or 0.2m + (-12 + 12) = (-32 + 12)

    making the equation look like this:

    0.2m = -20

    now we are going to divide 0.2 from both 0.2m and -20 to get the value of m:

    0.2m/0.2 = -20/0.2

    Thus getting the answer:

    m = -100

    So how do we know that -100 is the value of m? well we check our work of course by substituting -100 in place of m!

    ⅕(-100) – 12 = -32  or 0.2(-100) – 12 = 32

    0.2(-100) – 12 = 32

    -20 – 12 = -32

    -32 = -32
