Directions (Q.6-10) In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and give answer
1) if x > y
2) if x < y
3) if x ≥ y
4) if x ≤ y
5) if x = y or relation cannot be established between 'x' and 'y'.
6. I. 8x+y=10
II. 4x+2y=13
7. I. (x+3) (y+2)=12
II. 2xy+4x+5y=11
8. I. (3x-2)/y = (3x+6)/(y+16)
II.(x+2)/(y+4) = (x+5)/(Y+10)
9. I. x^2+20x+4=50-25x
II. y^2-10y-24=0
10. I. (x^2-10x+16)/(x^2 -12x +24) = 2/3
II. y^2-y-20=0

6.Ans-(2)
from both equation
x=7/12, y=16/3
y>x
7. Ans-(5)
xy+3y+2x +6 =12
2xy+6y+4x=12----(i)
2xy+5y+4x=11 ---- (ii)
From eq. (i) --- (ii)
Y = 1
From eq. (i)
x=1
x = y
8. Ans-(2)
(3x-2)/y = (3x+6)/(y+16)
48x-8y = 32 ---- (i)
(x+2)/(y+4) = (x+5)/(y+10)
y = 2x ---- (i)
From Equation (i) & (ii)
x=1, y=2
y>x
9.Ans-(5)
From the given Equation
x=1, -46
& y=-2,/2
x # y
10.Ans-(5)
From 1st equation
x^2-6x=0
x=0,6
From 2nd equation
(y+4) (y-5)
y=-4,5
x # y
