Respuesta :
-4 > x -7
Move the "-7" to the left hand side which will also change the sign
-4 + 7 > x ( "-4 + 7" is the same as "7 - 4")
3 > x OR x < 3 (3 is greater/bigger than x which also means x is smaller/lesser than 3)
They are both incorrect.

They are both incorrect.
Both students are wrong.
The correct solution to the inequality -4 > x - 7 is x < 3
The given inequality is -4 > x - 7
To solve the inequality -4 > x - 7, follow the steps below
Add 7 to both sides of the inequality
--4 + 7 > x - 7 + 7
3 > x
This can be re-written as:
x < 3
The two students got 28 < x and x > 28 which is different from x < 3 (the true solution). Therefore, they both are incorrect
