Answer:
The linear pair has infinite solutions.
Step-by-step explanation:
2x + 3y = 9
4x + 6y = 18
a1 = 2 b1 = 3 c1 = 9
a2 = 4 b2 = 6 c2 = 18
a1/a2 = 2/4 = 1/2
b1/b2 = 3/6 = 1/2
c1/c2 = 9/18 = 1/2
1/2 = 1/2 = 1/2
which means
a1/a2 = b1/b2 = c1/c2
which means the pair of linear equation is co incident
∴ the linear pair has infinitely many solutions.
