Full solution

Q. What value of y y makes the equation below true?\newline10y9=51 10 y-9=51 \newline66\newline1010\newline1212\newline1616
  1. Write Equation: Write down the equation that needs to be solved.\newline10y9=5110y - 9 = 51\newlineWe need to find the value of yy that makes this equation true.
  2. Add 99: Add 99 to both sides of the equation to isolate the term containing yy on one side.\newline10y9+9=51+910y - 9 + 9 = 51 + 9\newlineThis simplifies to:\newline10y=6010y = 60
  3. Divide by 1010: Divide both sides of the equation by 1010 to solve for yy.10y10=6010\frac{10y}{10} = \frac{60}{10}This simplifies to:y=6y = 6
