Answer:
The student did not add 4 to all sides of the inequality
Step-by-step explanation:
2<-3x - 4<5
Add 4 to all sides
4 + 2< -3x - 4 + 4 < 5 + 4
6< -3x < 9
Divide all sides by the coefficient of x; -3
-2< x < -3
Remember, when dividing an inequality with a negative number, you must flip the sign
So, this becomes;
-2 > x > -3
