If 6h - 7 < 5, then h < 2 what the counterexample

6h - 7 < 5
6h < 5

This means that 6 times h is less than 5.

h < 2 means that as long as h is less than 2, this inequality will be true.

A counterexample would be 1.

6h < 5
6(1) < 5
6 × 1 < 5
6 < 5

6 is not less than 5, therefore that inequality is not true and 1 proves to be a counterexample.
