2x + y + 10 = 0 (C.B.S.E. 1992)
Solution:
Question 3.
2x + y = 35
3x + 4y = 65 (C.B.S.E. 1993)
Solution:
Question 4.
2x – y = 6
x – y = 2 (C.B.S.E. 1994)
Solution:
Question 5.
x+yxy=2,x−yxy=6
Solution:
Question 6.
ax + by = a – b
bx – ay = a + b
Solution:
ax + by = a – b
bx – ay = a + b
Question 7.
x + ay = b
ax – by = c
Solution:
x + ay = b
Question 8.
ax + by = a2
bx + ay = b2
Solution:
Question 9.
Solution:
Question 10.
Solution:
Question 11.
Solution:
Question 12.
Solution:
Question 13.
xa+yb=a+b
xa2+yb2=2
Solution:
Question 14.
xa=yb
ax + by = a2 + b2
Solution:
Question 15.
2ax + 3by = a + 2b
3ax + 2by = 2a + b
Solution:
Question 16.
5ax + 6by = 28
3ax + 4by = 18
Solution:
Question 17.
(a + 2b) x + (2a – b) y = 2
(a – 2b) x + (2a + b) y = 3
Solution:
Question 18.
Solution:
Question 19.
Solution:
Question 20.
(a – b) x + (a + b) y = 2a2 – 2b2
(a + b) (x + y) = 4ab
Solution:
Question 21.
a2x + b2y = c2
b2x + a2y = d2
Solution:
Question 22.
ax + by = a+b2
3x + 5y = 4
Solution:
Hence x = 12 , y = 12
Question 23.
2 (ax – by) + a + 4b = 0
2 (bx + ay) + b – 4a = 0 (C.B.S.E. 2004)
Solution:
Question 24.
6 (ax + by) = 3a + 2b
6 (bx – ay) = 3b – 2a (C.B.S.E. 2004)
Solution:
Question 25.
a2x−b2y=0
a2bx−b2ay=a+b,x,y≠0
Solution:
Question 26.
mx – ny = m2 + n2
x + y = 2m (C.B.S.E. 2006C)
Solution:
Question 27.
Solution:
Question 28.
