Full solution

Q. Solve for mm.\newline2(m7)1=12(m - 7) - 1 = -1\newlinem=m = _____
  1. Simplify Equation: Simplify the equation by distributing the 22 into the parentheses.2(m7)1=12(m - 7) - 1 = -12m141=12m - 14 - 1 = -12m15=12m - 15 = -1
  2. Add 1515: Add 1515 to both sides to isolate the term with mm.\newline2m15+15=1+152m - 15 + 15 = -1 + 15\newline2m=142m = 14
  3. Divide to Solve: Divide both sides by 22 to solve for mm.2m2=142\frac{2m}{2} = \frac{14}{2}m=7m = 7
