$x in RR$

graph{y=|3x-7| [-10, 10, -5, 5]}

Let us have the graph of $y=|3x-7|$ .

From the graph, we observe that it lies above the X-axis.

This means # AAx in RR, y=|3x-7| >=0, and, bcz. 0>=-3,

$rArr AA x in RR, |3x-7| >=-3$

Hence, the Soln. $x in RR$

How do you solve │3x- 7 │≥-3│3x- 7 │≥-3?
