To solve the inequality 2|x + 1/3| < 9, we need to isolate the absolute value expression and then solve two separate inequalities.

First, we can divide both sides of the inequality by 2, which gives us |x + 1/3| < 4.5.

Next, we can split the absolute value inequality into two separate inequalities, one for the positive part and one for the negative part:

For the positive part: x + 1/3 < 4.5
Subtracting 1/3 from both sides, we get x < 4.5 - 1/3, which simplifies to x < 4.1667.

For the negative part: -(x + 1/3) < 4.5
Multiplying both sides by -1 (which flips the inequality sign), we get x + 1/3 > -4.5.
Subtracting 1/3 from both sides, we get x > -4.5 - 1/3, which simplifies to x > -4.8333.

So, the solution to the inequality 2|x + 1/3| < 9 is -4.8333 < x < 4.1667.

To graph the solution, we can draw a number line and mark the points -4.8333 and 4.1667 as open circles (since they are not included in the solution). Then, draw a solid line between these two points to represent the range of values that satisfy the inequality.
