How would this inequality be solved?
|7d| > -43
There is no reference to this type of problem in the textbook.
when d is positive, where is 7 d >-43
well whenever d >-43/7
when d is negative, when is |d|>-43
well whenever d < -43/7
in other words for all real d
the absolute value of any old number is positive.
It is greater than ANY negative number
