Q. Is m=−9m = -9 a solution to this equation?\newline−8−m=1-8 - m = 1\newlineChoices:\newline(A)yes\newline(B)no
  1. Identify Equation: We have the equation:\newline−8−m=1-8 - m = 1\newlineIdentify the equation after substituting m=−9m = -9.\newlineSubstitute −9-9 for mm in −8−m=1-8 - m = 1.\newlineEquation: −8−(−9)=1-8 - (-9) = 1
  2. Substitute mm: Simplify −8−(−9)-8 - (-9).\newline−8+9=1-8 + 9 = 1
  3. Simplify Expression: Calculate the result of −8+9-8 + 9.\newline1=11 = 1
  4. Calculate Result: We found: −8−(−9)=1-8 - (-9) = 1\newlineIs m=−9m = -9 a solution to the equation −8−m=1-8 - m = 1?\newlineFor m=−9m=-9, the equation becomes 1=11 = 1, which is true.\newlineSo, m=−9m = -9 is a solution to the equation −8−m=1-8 - m = 1.
