@pooja195 Could you help? :)
Well look at step two the mistake is obvious :-)
Did the student forgot to add the +8 at the end like in step 1?
Not very good at math, haha :)
Is it B?
yes! :O how did u get that O_o ?
It was a guess, xD
I got another one, mind seeing if im right?
not quite 12+4=?
Thought you had to subtract it :P
Thanks! I got some more, would you care to help me a little bit more? :D
try solving the first one.
First one is A (4)?
No no I mean c (8)
yes thats correct c
And the second is "It has NO solution"?
Nope try solving it
Stop guessing and actually try
-_- did u even try?
Yeah? Was I wrong? .-.
told you I suck at math :p
−2a + 2a + 7 = 8, that has infinitely solutions
thnks for the link ^_^
