Write a two-column proof.
Given: 7y=8x-14; y=6
Prove: x=7
I need help making a two-column proof with the statements and the reasons, please! Thank you! ( This is what I have so far)
Statements | Reasons
1. 7y=8x-14;y=6 | Given
2. 7(6)=8x-14 | Substitution
3. ????|????
4. ????|????
5. x=7| ????
(I just stopped at 5 for right, that's not the exact steps I think the two-column proof actually has)
Thank you again for whoever helps me! Be Blessed

To me a two column proof is usually associated with Euclidean Geometry.
To use it here in this rather simplistic problem is like using a sledge hammer to drive in a finishing nail ...
here is what I would do
7y=8x-14; y=6
then:
42 = 8x - 14
56 = 8x
x = 56/8 = 7
There! I have proven it.
All that other stuff is just "word salad" to me.

It has to do with so-called addition property of equality and division property of equality.
Basically, if two things are equal,
adding or dividing both things by the same amount does not affect their equality.

Given - 7y=8x-14 : y=6
Substitution Property - 7(6)=8x-14
Distributive Property - 8x-14=42
Addition Property - 8x=56
Division Property - x=7
Substitution Property - 7(6)=8x-14
Distributive Property - 8x-14=42
Addition Property - 8x=56
Division Property - x=7
