What do you think who is incorrect?

mathsucks321 · Answer

Julie?

mathsucks321 · Answer

Students were asked to write two equations that represent the same formula and we are looking for the student who got it wrong.
Think of Darren's  as this: 10 = 7+ 3 = 3= 10 - 7.  Then that means Darren's is correct.
Think of Brenda's as 5= 10/2= 10= 2 x 5
So Darren and Brenda's are correct.
What else..?
