_______________________________
8u - 3v = 5uv... Equation ( i )
6u - 5v = -2uv.... Equation ( ii )
Multiply Equation i by 2 and second by 5
=>
16u - 6v = 10uv
30u - 25v = -10uv
_____________
46u = 31v
=>
u = 31v/46 ... Equation ( iii )
Substitute value of u in Equation ( ii )
6 × ( 31v/46 ) - 5v = -2 × ( 31v² ) / 46
=>
186 - 230 = - 62v
=>
v = 44/62
=>
v = 22/31
Now, put value of v in Equation ( iii )
=>
u = (31 × 22 )/ 31×46
=>
u = 11/23
