Step-by-step explanation:

Step 1: Define Equation

-243 = -9(10 + x)

Step 2: Solve for x

1. Divide -9 on both sides:                    27 = 10 + x
2. Isolate x:                                             17 = x
3. Rewrite:                                              x = 17

Step 3: Check

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

1. Substitute in x:                    -243 = -9(10 + 17)
2. Add:                                     -243 = -9(27)
3. Multiply:                               -243 = -243

Here we see that -243 does indeed equal -243.

∴ x = 17 is the solution to the equation.
