Solve \(5(4m + 1) - 2m = -13\).

A. \(m = -\frac{14}{18}\)
B. \(m = -\frac{18}{20}\)
C. \(m = -1\)
D. \(m = -2.25\)

Answer :

Final answer:

The solution to the equation 5(4m + 1) - 2m = -13 is m = -1 after distributing, combining like terms, and solving for m. So,option (c) is the correct answer.

Explanation:

To solve the equation 5(4m + 1) - 2m = -13, we need to apply the distributive property and then simplify the equation to solve for m.

  1. Distribute the 5 into the parenthesis: 5 * 4m + 5 * 1 - 2m = -13 which simplifies to 20m + 5 - 2m = -13.
  2. Combine like terms on the left side of the equation: (20m - 2m) + 5 = -13 simplifies to 18m + 5 = -13.
  3. Subtract 5 from both sides: 18m = -18.
  4. Divide both sides by 18 to solve for m: m = -18 / 18, which simplifies to m = -1.

Therefore, the solution to the equation is m = -1, which corresponds to answer option (c).
