Equality Properties

Explanation:

Step 1: Define

4r - 6 = 6

Step 2: Solve for r

1. Add 6 to both sides: 4r = 12
2. Divide 4 on both sides: r = 3

Step 3: Check

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

1. Substitute in r: 4(3) - 6 = 6
2. Multiply: 12 - 6 = 6
3. Subtract: 6 = 6

Here we see that 6 does indeed equal 6.

∴ r = 3 is the solution to the equation.
