Given Equation is 2x + ay - 1 = 0 ----- (1)
On comparing with a1x + b1y + c = 0, we get
a1 = 2, b1 = a, c1 = -1
Given Equation is 3x - 5y - 7 = 0 ---- (2)
On comparing with a2x + b2y + c = 0, we get
a2 = 3, b2 = -5, c2 = -7.
Given that the Equation will have a unique solution:
a1/a2 = b1/b2
2/3 = a/-5
a = -10/3.
(ii)
Given that the Equation has many solutions:
a1/a2 = b1/b2 = c1/c2
2/3 = a/-5 = -1/-7
No value of a.
Hope this helps!
