Write a two-column proof. Given: 7y = 8x – 14; y = 6 Prove: x = 7
WELL WHAT DOO YOU KNOW?
Well, let's see. I am pretty sure I can substitute here. Sorry, I am not that good at math. Could I do 7(6)=8(7)-14?
well everything is correct exept you can not put 7 in for x since that is what you are trying to prove
Oh! Alrighty! I think I now got it from here that now I know I am half way correct. Thank you!
your welcome let me know if you need more help:)
