Step-by-step explanation:

Step 1: Define

-29 = 9 - 6k - 2k - 1

Step 2: Solve for k

1. Combine like terms:                                                                                       -29 = 8 - 8k
2. [Subtraction Property of Equality] Subtract 8 on both sides:                      -37 = -8k
3. [Division Property of Equality] Divide -8 on both sides:                              37/8 = k
4. Rewrite/Rearrange:                                                                                        k = 37/8

Step 3: Check

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

1. Substitute in k:                                                                                                -29 = 9 - 6(37/8) - 2(37/8) - 1
2. Multiply:                                                                                                           -29 = 9 - 111/4 - 37/4 - 1
3. Subtract:                                                                                                          -29 = -75/4 - 37/4 - 1
4. Subtract:                                                                                                          -29 = -28 - 1
5. Subtract:                                                                                                          -29 = -29

Here we see that -29 does indeed equal -29.

∴ k = 37/8 is the solution to the equation.
