Q. If −x−10y=9 -\mathbf{x}-\mathbf{1 0 y}=\mathbf{9} is a true equation, what would be the value of −10y−x -\mathbf{1 0 y}-\mathbf{x} ?\newlineAnswer:
  1. Identify Given Equation: Identify the given equation and the expression we need to find the value of.\newlineGiven equation: −x−10y=9-x - 10y = 9\newlineExpression to find: −10y−x-10y - x
  2. Rearrange Terms: Notice that the expression we need to find the value of is just a rearrangement of the terms in the given equation.\newlineRearrange the terms in the given equation to match the expression we need to find.\newline−x−10y=9-x - 10y = 9 can be rewritten as −10y−x=9-10y - x = 9
  3. Find Value: Since the rearranged expression is equivalent to the given equation, the value of the expression will be the same as the value of the given equation.\newlineTherefore, the value of −10y−x-10y - x is 99.
