Hi guys! I just had a overdue assignment in math. I am a little lost in this topic, so I was hoping someone could help me out? Thanks!
Tell whether each equation is true, false, or open. Explain.
1. 6 - t = 12
2. 7 + (-5) = 12
3. 31 - 15 = 22 + (-3)2
If anyone knows how to figure out these equations, I would love to have them share. Thank you!

Okay, I was working some of them out. I believe that #1 is a true equation, but I am not for sure.
Oops, sorry meant false. Is it correct?
#1 is open
It can be true or false, depending on the value of t.
Now check the others to see whether they are always true or always false. That is, evaluate both sides.
