II. y^2 – 2y = 0
or, y(y -2) = 0
y = 0, 2
i.e. no relationship between x and y.

28. I. x^2 – 5x + 6 = 0
II. 2y^2 – 15y + 27 = 0

a)
b)
c)
d)
e)

or, (x -2) (x -3) = 0
x =2, 3
II. 2y^2 - 6y - 9y + 27 = 0
or, 2y(y - 3)-9(y -3) = 0
or, (y- 3) (2y -9) = 0
y = 3, 9/2
hence, x ≤ y

29. I. 3x + 2y = 301
II. 7x – 5y = 74

a)
b)
c)
d)
e)
I. eqn (I) × 5 + eqn (II) × 2
[15x + 10y = 1505] + [14x – 10y = 148] = 29x = 1653
x = (1653/29) = 57
and y = 65
hence, x< y
