Where did this student make the mistake when solving this inequality?
-2x - 3 > 5x + 4
-2x -2x
-3 > 3x - 5
+5 +5
2 > 3x
/3 /3 (divide by 3)
2/3 > x
Question 1 options:
2x needed to be added to both sides to move the entire term to other side of the inequality sign to combine like terms.
5 should have been subtracted from both sides of the inequality since I am combining like terms.
When dividing by 3 you need to switch the sign.
When subtracting 2x to both sided of the inequality, you should switch the sign.
