Step-by-step explanation:

Step 1: Define equation

5x - (x + 4) + 1 = 3 - 2(x + 6)

Step 2: Solve for x

Distribute:                          5x - x - 4 + 1 = 3 - 2x - 12Combine like terms:          4x - 3 = -2x - 9Add 2x on both sides:      6x - 3 = -9Add 3 to both sides:         6x = -6Divide both sides by 6:     x = -1

Step 3: Check

Plug in x to verify it's a solution.

Substitute:                    5(-1) - (-1 + 4) + 1 = 3 - 2(-1 + 6)Parenthesis (Add):        5(-1) - 3 + 1 = 3 - 2(5)Multiply:                        -5 - 3 + 1 = 3 - 10Subtract:                       -8 + 1 = -7Add:                              -7 = -7

Wow. that is a really cool question.
