Find the value of x and y, when
i.
If ,
Then a=e, b=f, c=g, d=h
Given
So, x + y = 8 and x - y = 4
Adding these two gives 2x = 12
y =2
Conclusion : x = 6 and y =2
ii.
Given,
So, 2x+5 = x-3 and 3y-7 = -5
Conclusion : x = -8 and y =
iii.
2x+3 = 7
2y-4 = 14
Conclusion : x = 2 and y = 9
(Given answer is wrong)
