If equation of line p is x + y = 5 and that of line q is x – y = 3, what are the coordinates of the point common to both the lines?
A.(2, 3)
B.(4, 1)✓ Correct
C.(2, 1)
D.(1, 4)
Explanation
Solving x + y = 5 and x – y = 3 simultaneously: adding both gives 2x = 8, so x = 4. Substituting back: 4 + y = 5, so y = 1. The point of intersection is (4, 1).
