Let's simplify and solve the equation step by step. First, combine like terms: \( 6m - 4m + 1 = -7 \) which simplifies to \( 2m + 1 = -7 \). Next, subtract 1 from both sides to isolate the term with \( m \): \( 2m = -8 \). Finally, divide both sides by 2 to find \( m = -4 \). Always double-check your work! It's easy to make a small mistake when moving terms around. For instance, forgetting to change the sign when moving a term to the other side can lead you down the wrong path. So, take a moment to review your steps and confirm your result. Happy solving!
