I hope so this ans will be correct
it's 5 multiple to eq.2
Answer:
1. 5x - 2y - 8 = 0 -------------------------------- (i)
2. 2x - 5y - 12 = 0 -------------------------------(ii)
Now, in eq(i) ,
5x - 2y - 8 = 0
=> 5x = 8 + 2y
=> x = (8+ 2y ) /5 ---------------------------------(iii)
Now putting the value of x from eq(III) in eq(ii), we get,
2x - 5y - 12 = 0
=> 2[( 8 + 2y )/5] - 5y = 12
=> [(16 + 4y) /5 ] - 5y = 12
=> 16 + 4y - 25y = 60
=> -21y = 44
=> y = -44/21 --------------------------------------------- (iv)
Now ,
putting the value of y in eq(iii), we get
x = [8 + 2 ( -44/21 )]/5
=> x = (168 - 88)/105
=> x = 80/105
=> x = 16/21
∴ x = 16/21 and y = -44/21 (Ans.)
