A.A.24 Algebraic equation & Inequalities How Braulio, Numan, Monshur, and Willy solved an algebraic inequality in their UR

2
The problem Solve for X:

3
Willy: Why do you change the sign from (is greater than)? Braulio: You need to change the sign when you are solving problems with inequality signs. Willy: But why?

4
Monshur: Look [point to the text] you don’t change the sign. Numan: You don’t have to change the sign, but I don’t know why The problemExample from UR

5
Willy: I learned that you change the sign (inequality) when you divided by a negative number, but here you divided by positive 4, so keep the sign. Willy’s Ah-Ha Moment!!

6
Our Take Away (1) If each side of an inequality is divided by the negative number, then change the sign. (2) They referenced to an existing example.
