Step-by-step explanation:

Step 1: Define

-2(x + 5) = -2(x - 2) + 5

Step 2: Solve for x

1. Distribute -2:                    -2x - 10 = -2x + 4 + 5
2. Add:                                  -2x - 10 = -2x + 9
3. Add 2x on both sides:     -10 ≠ 9

Here we see that -10 does not equal 9.

∴ x = no solutions.
