Q. Find the missing number so that the equation has infinitely many solutions. \newline−2x−20=‾x−20-2x - 20 = \underline{\hspace{1cm}}x - 20
  1. Identify Identical Expressions: To determine the missing number that will result in the equation having infinitely many solutions, we need to make the expressions on both sides of the equation identical. This means that the coefficients of xx and the constant terms on both sides must be the same.
  2. Ensure Equal Coefficients: The given equation is -2x - 20 = ____x - 20. For the equation to have infinitely many solutions, the coefficient of xx on the left side must be equal to the coefficient of xx on the right side. Since the coefficient on the left side is −2-2, the missing number on the right side must also be −2-2.
  3. Set Coefficients to Match: By setting the missing coefficient to −2-2, we get the equation −2x−20=−2x−20-2x - 20 = -2x - 20. Now both sides of the equation are identical, which means the equation will have infinitely many solutions.
