1. **Problem Statement:**
We are given inequalities from the transportation problem:
(2) 5 – x ≥ 0
(3) 5 – y ≥ 0
(4) 8 – (x + y) ≥ 0
(5) x + y – 4 ≥ 0
We need to rewrite these inequalities by separating variables on the left and constants on the right.
2. **Rewrite each inequality:**
- For (2):
$$5 - x \geq 0$$
Subtract 5 from both sides:
$$5 - x - 5 \geq 0 - 5$$
Simplify:
$$-x \geq -5$$
Multiply both sides by $-1$ (remember to reverse inequality):
$$\cancel{-}x \leq \cancel{-}5$$
$$x \leq 5$$
- For (3):
$$5 - y \geq 0$$
Subtract 5 from both sides:
$$5 - y - 5 \geq 0 - 5$$
Simplify:
$$-y \geq -5$$
Multiply both sides by $-1$ (reverse inequality):
$$\cancel{-}y \leq \cancel{-}5$$
$$y \leq 5$$
- For (4):
$$8 - (x + y) \geq 0$$
Distribute minus:
$$8 - x - y \geq 0$$
Subtract 8 from both sides:
$$8 - x - y - 8 \geq 0 - 8$$
Simplify:
$$-x - y \geq -8$$
Multiply both sides by $-1$ (reverse inequality):
$$\cancel{-}x + \cancel{-}y \leq \cancel{-}8$$
$$x + y \leq 8$$
- For (5):
$$x + y - 4 \geq 0$$
Add 4 to both sides:
$$x + y - 4 + 4 \geq 0 + 4$$
Simplify:
$$x + y \geq 4$$
3. **Final inequalities:**
$$x \leq 5$$
$$y \leq 5$$
$$x + y \leq 8$$
$$x + y \geq 4$$
These inequalities define the feasible region for the transportation problem.
**Answer:**
(2) $x \leq 5$
(3) $y \leq 5$
(4) $x + y \leq 8$
(5) $x + y \geq 4$
