Q. Which property of equality is shown below?\newlineIf: 71j=2171 - j = 21\newlineThen: (71j)k=21k(71 - j)k = 21k\newlineChoices:\newline(A) Addition Property of Equality\newline(B) Subtraction Property of Equality\newline(C) Multiplication Property of Equality\newline(D) Division Property of Equality
  1. Identify Operation: Identify the operation applied to both sides of the initial equation.\newlineThe initial equation is 71j=2171 - j = 21. The operation applied to both sides involves multiplication by 'kk'.
  2. Property of Equality: Determine which property of equality corresponds to the operation identified in step 11.\newlineSince we are multiplying both sides of the equation by the same value kk, the property of equality being used is the Multiplication Property of Equality.
