1 answer

To solve the equation \(8(2m + 3) = 120\) using inverse operations, let's break it down step by step.

  1. Distribute or simplify the equation.
    First, divide both sides of the equation by 8 to isolate the term with \(m\).

    \[ 2m + 3 = \frac{120}{8} \]

    Simplifying the right-hand side, we get:

    \[ 2m + 3 = 15 \]

  2. Subtract 3 from both sides.
    Next, we will subtract 3 from both sides to further isolate the term with \(m\).

    \[ 2m = 15 - 3 \]

    Simplifying gives us:

    \[ 2m = 12 \]

  3. Divide by 2.
    Finally, divide both sides by 2 to solve for \(m\):

    \[ m = \frac{12}{2} \]

    Simplifying this gives:

    \[ m = 6 \]

The solution to the equation \(8(2m + 3) = 120\) is \(m = 6\).


However, as I don't have the ability to utilize a sketch pad or create visual representations, I encourage you to sketch the work out as:

  • Start with the original equation.
  • Show each step with arrows indicating the operations performed, such as division and subtraction.
  • Conclude with the final answer \(m = 6\).

If you have access to graphing tools or sketching software, you can illustrate the steps as outlined above to visualize the solution process!
