Step-by-step 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.
