Here is what I got to do : write an inequality for my classmates to solve. In my inequality, use both the multiplication and addition properties of inequalities; before I summit this to class I want to know if I did it right: 5(x + 8) 6 > 4(x + 6);
5x + 40  6 > 4x + 24; 5x + 44  44 > 4x + 24  44; 5x  4x > 4x  4x 20; 1x/1 < 20/1; x<20, is this right?

5(x + 8) 6 > 4(x + 6);
5x + 40  6 > 4x + 24;
5x + 44  44 > 4x + 24  44;
5x  4x > 4x  4x 20;
1x/1 < 20/1; Where in the world did you get this step? You did not divide by a negative.

I got 5x4x> 4x  4x20; 1x< 20; you have to get x by itself so you divide both side by 1; 1x/1 < 20/1; x< 20 that is how I got x<20

Solve the system of inequalities. y<2x+4 3x  2y> 6 So I just want y alone. For the second inequality, I added 3x to both sides and got 2y> 3x+6. Then I divided both sides by 2. I got y> 3/2  3 Do I have to switch …
