    Answer:

    m = 7

    Step-by-step explanation:

    To answer this question, we first have to simplify each side of the equation:

    10m – 3 (2m – 9) = 9 (m – 1) + 1

    10m – 6m + 27 = 9m – 9 + 1

    4m + 27 = 9m – 8

    Now, we have to take the 8 away from the right side by adding it onto the left side:

    4m + 27 = 9m – 8

           +8            +8

    4m + 35 = 9m

    Now, we subtract 4m from the left side in order keep the variable on one side:

    4m + 35 = 9m

    -4m          -4m

    35 = 5m

    Finally, we divide 35 by 5 to isolate the variable:

    5m = 35

    /5      /5

    m = 7

    And now we now that m = 7

    Hope this helps! 🙂
