Equality Properties

Step-by-step explanation:

Step 1: Define Equation

3x - 6 = 9

Step 2: Solve for x

  1. Add 6 to both sides:                    3x = 15
  2. Divide 3 on both sides:                x = 5

Step 3: Check

Plug in x into the original equation to verify it's a solution.

  1. Substitute in x:                    3(5) - 6 = 9
  2. Multiply:                               15 - 6 = 9
  3. Subtract:                              9 = 9

Here we see that 9 does indeed equal 9.

∴ x = 5 is the solution to the equation.
