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.

  • Algebra -

    I got 5x-4x> 4x - 4x-20; 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

  • Algebra -

    I agree with your 5x-4x> 4x - 4x-20;
    that simplifies to x>-20
    From there, your work makes no sense, and is in fact wrong. Dividing by 1 does not reverse the inequality sign

    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 …
