Q. If 9x+y=−1 \mathbf{9 x}+\mathbf{y}=-\mathbf{1} is a true equation, what would be the value of −5+9x+y -\mathbf{5}+\mathbf{9 x}+\mathbf{y} ?\newlineAnswer:
  1. Given Equation: We are given the equation 9x+y=−19x + y = -1 and we need to find the value of −5+9x+y-5 + 9x + y. Let's substitute the value of 9x+y9x + y from the given equation into the expression −5+9x+y-5 + 9x + y.
  2. Substitute Values: Substitute 9x+y9x + y with −1-1 in the expression −5+9x+y-5 + 9x + y.\newline−5+9x+y=−5+(−1)-5 + 9x + y = -5 + (-1)
  3. Simplify Expression: Now, simplify the expression by combining the constants. −5−1=−6-5 - 1 = -6
  4. Final Value: The value of −5+9x+y-5 + 9x + y is therefore −6-6.
