Direction (26-30): In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and given answer:
a) if x< y
b) if x> y
c) if x โค y
d) if x โฅ y
e) if x = y, or relationship between x and y can't be established.

26. I. 7x^2 - 33x + 20 = 0
II. 7y^2 + 9y โ 10 = 0

a)
b)
c)
d)
e)
I. 7x^2 - 33x + 20 = 0
or, 7x^2 - 28x - 5x + 20 = 0
or, 7x(x - 4) - 5(x โ4)= 0
or (7x - 5) (x - 4) = 0
or, x = 4, (5/7)
II. 7y^2 + 9y -10 = 0
or, 7y^2 + 14y - 5y โ 10 = 0
or, 7y(y + 2) - 5(y + 2) = 0
or, (7y - 5)(y + 2) = 0
or, y = 5/7, -2
Hence, x โฅ y

27. I. 7x + 3y = 8
II. 3x + 2y = 12

a)
b)
c)
d)
e)
I. 7x + 3y = 8
II. 3x + 2y = 12
Now, solving both the eqns, we get
eqn (i) x 2 - eqn (ii) x 3
(14x+ 6y=16) โ (9x + 6y = 36)
5x = -20
x = -4 and y = 12
Hence, x

28. I. x^2 = 289
II. y = 3โ2197

a)
b)
c)
d)
e)
I. x^2 = 289
or x = ยฑ17
II. y = 3โ2197
y = 13
Hence, we canโt find a relationship between x and y.

29. I. 8x^2 - 11x + 3 = 0
II. y^2 - 8y + 7 = 0

a)
b)
c)
d)
e)
8x^2 -11x + 3 = 0
or, 8x^2 - 8x - 3x +3 = 0
or, 8x(x - 1) - 3(x - 1) = 0
or, (8x -3)(x - 1) = 0
or, x =1, 3/8
II. y^2 - 8y + 7 = 0
or, y^2 - y - 7y + 7 = 0
or, y(y - 1) - 7(y - 1) = 0
or, (y - 1) (y - 7) = 0
or, y = 1, 7
Hence, x โค y

30. I. x = โ1089
II. y + y โ 756 = 0

a)
b)
c)
d)
e)
I. x = โ1089
or, x = 33
II. y^2 + y - 756 =0
or, y^2 + 28y - 27y - 756 = 0
or, y(y +28) - 27(y + 28) = 0
or, (y - 27)(y + 28) = 0
or, y= 27, -28
Hence, x> y
