Concept:The common region is the intersection of half-planes defined by the given lines and non-negativity constraints.
Explanation:1. The lines
x+y=6 and
2x−y=2 intersect at
(38,310), which lies in the first quadrant.
2. In the first quadrant (
x≥0,y≥0), the two lines and the axes form a bounded triangular region with vertices
(1,0),
(38,310), and
(6,0).
3. This bounded region lies below the line
x+y=6 (so
x+y≤6) and below the line
2x−y=2 (so
2x−y≥2, since
2x−y≥2 rearranges to
y≤2x−2).
4. The origin
(0,0) does not satisfy
2x−y≥2, confirming the region excludes the origin.
Thus, the inequalities are
x+y≤6,
2x−y≥2,
x≥0,
y≥0.
