Q. If −3x+5y=−8 -3 x+5 y=-8 is a true equation, what would be the value of −3x+5y−4 -3 x+5 y-4 ?\newlineAnswer:
  1. Identify Equation and Expression: Identify the given equation and the expression to evaluate.\newlineWe are given that −3x+5y=−8-3x + 5y = -8 is a true equation, and we need to find the value of −3x+5y−4-3x + 5y - 4.
  2. Substitute Value: Substitute the value of −3x+5y-3x + 5y into the expression −3x+5y−4-3x + 5y - 4. Since −3x+5y=−8-3x + 5y = -8, we can replace −3x+5y-3x + 5y with −8-8 in the expression −3x+5y−4-3x + 5y - 4. So, −3x+5y−4-3x + 5y - 4 becomes −8−4-8 - 4.
  3. Calculate Expression: Calculate the value of the expression −8−4-8 - 4.\newlinePerform the subtraction: −8−4=−12-8 - 4 = -12.
