Explanation:

Step 1: Define

-8 = 16x + 9

Step 2: Solve for x

1. [Subtraction Property of Equality] Subtract 9 on both sides: -17 = 16x
2. [Division Property of Equality] Divide 16 on both sides: -17/16 = x
3. Rearrange/Rewrite: x = -17/16

Step 3: Check

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

1. Substitute in x: -8 = 16(-17/16) + 9
2. Multiply: -8 = -17 + 9
3. Add: -8 = -8

Here we see that -8 does indeed equal -8.

∴ x = -17/16 is the solution to the equation.
