x= 4, 5 ...(1)
From II, y^2 = 13y - 42
Y^2 - 13y + 42 = 0
(y - 7)(y - 6) = 0
y = 7, 6 ...(2)
From (1) and (2), we have y> x.

a)
b)
c)
d)
e)
From I, 2x^2 =128
X^2 = 64
x = √64 = 8 or -8 …..(1)
From II, y^2 - 10y + 25 = 0
Y^2 - 5y - 5y + 25 = 0
(y – 5) (y - 5) = 0
y = 5, 5 ….(2)
From 1 and 2 there is no relation between x and y.

30. I. x^2 – 5x + 6 = 0
II. y^2 + 24 = 10y

a)
b)
c)
d)
e)
I. x^2 - 3x – 2x + 6 = 0
x (x - 3) - 2(x - 3) = 0
(x - 3)(x - 2) = 0
x = 3, 2
y^2 -10y + 24 = 0
y^2 - 6y – 4y + 24 = 0
y (y - 6) - 4(y - 6) = 0
(y - 6) (y - 4) = 0
y = 6, 4
Therefore, x< y.
