Wow! um, well what don't you get about that? =)
OpenStudy (igreen):
Let's try the first question..
OpenStudy (igreen):
2x + 4 = -3x + 14
2x + 4 + 3x = -3x + 14 + 3x
What did he do here?
OpenStudy (igreen):
Correct.
OpenStudy (igreen):
Yes!

5x + 4 -4 = 14 -4

What did you do here?
OpenStudy (igreen):
Yes, and you said he added 4, so that's where he was wrong.
OpenStudy (igreen):
Just say on the fourth step, Splott added 4 to both sides when he should have divided.
OpenStudy (igreen):
Look at Fizzle's work and see if he did something wrong, if he did tell me what it is, if he didn't tell me he didn't.
OpenStudy (igreen):
Actually, I see something wrong.

2 things actually..
OpenStudy (igreen):
Yes!
OpenStudy (igreen):
But he actually made two mistakes..
-12 = -5x
He has to divide -5 to both sides, but he added it..so you can say he was wrong on Line 5 and Line 6.
