3x + 1 3x + 7-3x -13 < x +73x + 3 < x 1(2x-3) < 2

3x + 1 < 4x 78x 5 5x + 15x + 23 > 3x + 7-3x -13 < x +73x + 3 < x 1(2x-3) < 210 < 3x + 4 < 19Thanks for the post. Your number one example is very interesting. That was a good and interesting math creation. I tried solving it with my method and it came to the same answer you have already which is 4<=x. The second example of >=2; I am not very sure of how you meant it. And the sign you mentioned in your second paragraph I do not understand what you meant by that either. Could you please throw more lights on these two areas. I would love to understand how you meant them. I will need some class colleagues to brainstorm on some difficult math problems and ascertain how they apply to our day to day life activities as time goes on. For the meantime what is the difference between 1/2 x 2/1 and 1/2 = 2/1.
