Question
Solve the given inequality and show the graph of the solution on number line:
3(1 – x) < 2 (x + 4)
Solution
3(1 - x) < 2 (x + 4)
= 3 - 3x < 2x + 8
= 3 - 8 < 2x + 3x
= -5 < 5x
= `(-5)/5 < (5x)/5`
= -1 < x
The graphical representation of the solutions of the given inequality is as follows.

The longest side of a triangle is 3 times the shortest side and the third side is 2 cm shorter than the longest side. If the perimeter of the triangle is at least 61 cm, find the minimum length of the shortest side.
A man wants to cut three lengths from a single piece of board of length 91 cm. The second length is to be 3 cm longer than the shortest and the third length is to be twice as long as the shortest. What are the possible lengths of the shortest board if the third piece is to be at least 5 cm longer than the second?
[Hint: If x is the length of the shortest board, then x, (x + 3) and 2x are the lengths of the second and third piece, respectively. Thus, x = (x + 3) + 2x ≤ 91 and 2x ≥ (x + 3) + 5]
