Full solution

Q. What value of yy is a solution to this equation?\newline9y=99y = 9\newlineChoices:\newline(A) y=1y = 1\newline(B) y=2y = 2
  1. Given Equation: Start with the given equation.\newline9y=99y = 9\newlineTo find the value of yy, we need to isolate yy on one side of the equation.
  2. Isolate yy: Divide both sides of the equation by 99 to solve for yy.9y9=99\frac{9y}{9} = \frac{9}{9}y=1y = 1
  3. Solve for yy: Check the solution by substituting y=1y = 1 back into the original equation.\newline9×1=99 \times 1 = 9\newline9=99 = 9\newlineThe left side of the equation equals the right side, confirming that y=1y = 1 is a solution.
