Full solution

Q. if x−9=1x- 9 = 1, what is the value of xx ?
  1. Identify Equation: Identify the equation that needs to be solved.\newlineThe equation given is x−9=1x - 9 = 1. We need to find the value of xx.
  2. Add 99: Add 99 to both sides of the equation to isolate xx on one side.\newlinex−9+9=1+9x - 9 + 9 = 1 + 9\newlineThis simplifies to x=10x = 10.
  3. Check Solution: Check the solution by substituting the value of xx back into the original equation.10−9=110 - 9 = 1 This simplifies to 1=11 = 1, which is true.
