Step-by-step explanation:

Step 1: Define

Identify

x + (3x - 4) = 5 - (-7 - 3x)

Step 2: Solve for x

[Distributive Property] Distribute negative:                                                    x + 3x - 4 = 5 + 7 + 3x[Addition] Combine like terms:                                                                        4x - 4 = 12 + 3x[Subtraction Property of Equality] Subtract 3x on both sides:                      x - 4 = 12[Addition Property of Equality] Add 4 on both sides:                                     x = 16

16x-8 can be 8(2x-1) the distributive property hope it helps
