Q. Solve for xx. \newlinex−9=1x-9=1
  1. Identify Goal: Identify the goal of the problem, which is to solve for xx in the equation x−9=1x - 9 = 1.
  2. Add 99: Add 99 to both sides of the equation to isolate the variable xx on one side. This gives us x−9+9=1+9x - 9 + 9 = 1 + 9.
  3. Simplify Equation: Simplify both sides of the equation. On the left side, −9+9-9 + 9 equals 00, so we are left with xx. On the right side, 1+91 + 9 equals 1010. The equation now is x=10x = 10.
  4. Check Solution: Check the solution by substituting xx with 1010 in the original equation to see if the left side equals the right side. Substituting gives us 10−910 - 9, which equals 11. Since the right side of the equation is also 11, the solution x=10x = 10 is correct.
