Full solution

Q. Which property of equality is shown below?\newlineIf: 91=h(79)-91 = h - (-79)\newlineThen: 791=7(h(79))-7 \cdot -91 = -7(h - (-79))
  1. Analyze Given Statements: Analyze the given statements.\newlineIf: 91=h(79)-91 = h - (-79)\newlineThen: 791=7(h(79))-7 \cdot -91 = -7(h - (-79))\newlineWe need to identify which operation is applied to both sides of the equation.
  2. Identify Operation Used: Identify the operation used.\newlineThe operation used is multiplication by 7-7 on both sides of the equation.\newline91-91 is multiplied by 7-7, and the entire expression h(79)h - (-79) is also multiplied by 7-7.
  3. Determine Property of Equality: Determine the property of equality.\newlineBy multiplying both sides of the equation by the same number (7(-7), the equation remains balanced. This is known as the "Multiplication Property of Equality."
