Step-by-step explanation:

Step 1: Define

-2/7w = 8

Step 2: Solve for w

1. [Division Property of Equality] Divide both sides by -2/7:                           w = -28

Step 3: Check

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

1. Substitute in w:                    -2/7(-28) = 8
2. Multiply:                                8 = 8

Here we see that 8 does indeed equal 8.

∴ w = -28 is the solution to the equation.
