what is 3x<5x

Question

how do I solve this problem 

Answer 1

3x<5x

 

0 < 2x     We may add/subtract positive values and retain the sense of the inequality.

0 < x       We may multiply/divide by positive values and retain the sense of the inequality.

 

This inequality is true for any value of x greater than 0.

 

 

Answer 2

3x < 5x             divide both sides by x

3 < 5                false statement, no solution
