6x - 3y = - 10 .......eq (i)
3x + 5y = 8 ....... multiplying the whole eq with 2 .....then the equation becomes...
=( 3 x + 5y = 8 )×2
= 6x + 10y = 16 ........eq (ii)
subtracting eq (ii) from eq(i)
6x + 10y = 16
6x - 3y = 8
_________
0 +13y = 8
_________
y = 8/13
then eq(i) becomes .....
6x - 3 × (8/13) = -10
6x - 24/13 = -10
6x = -10 + 24/13
6x = ( -130 +24 )/13
6x = (-106)/13
x = -106/78
x = -53/39
HENCE THE VALUE OF X AND Y ARE -53/39 AND 8/13 RESPECTIVELY
