Equality Properties

Explanation:

Step 1: Define equation

3x - 5 = 9

Step 2: Solve for x

1. Add 5 to both sides: 3x = 14
2. Divide 3 on both sides: x = 14/3

Step 3: Check

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

1. Substitute in x: 3(14/3) - 5 = 9
2. Multiply: 14 - 5 = 9
3. Subtract: 9 = 9

Here we see that 9 does indeed equal 9.

∴ x = 14/3 is a solution of the equation.
