Write a two column proof. given: 7y=8x-14 ; y=6 prove: x=7

THIS IS THE BEST ANSWER 👇

7y = 8x – 14

7y = 7 (6) Reason: given

7y = 42

8x -14 = 42 Reason: Because 8x – 14 equals 7y

8x = 42 + 14 Reason: Because we flip 14 on the other side of the equation, so it becomes contrary to what it was.

8x = 56

× = 7
