Question

So i need reasons for each of these i legit have no idea how to do proofs

3x - 4 = 2(x + 8)

3x - 4 = 2x + 16

3x = 2x + 20

x = 20

they are in order

Answer 1

yes they are in order

Answer 2

`\begin {array}l\underline{\quad Statement\quad&\underline{\qquad Reason\qquad}&\underline{\qquad Side\ Note\qquad}\\ 3x-4=2(x+8)&\text{Given}&\\3x-4=2x+16&\text{Distributive Property}&\text{multiplied 2 into x+8}\\3x=2x+20&\text{Addition Property}&\text{added 4 to both sides}}\\x=20&\text{Subtraction Property}&\text{subtracted x from both sides}\\\end{array}`

NOTE:

The Statement is what was provided, Reason is the justification (proof), Side Note is JUST FOR YOU so you understand why the answer for the Reason was chosen.
