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
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
Id rather be sleeping rn but instead i have 58 overdue assignments to do kill me
dude i hate geometry algebra is way easier to cheat
I find it funny this a 10th grade math question, and this was 5 years ago, the person who asked it dude/girl prob 20 by now lool
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.
