Hello friend
__________________________
=) In the example
3x + y = 5 ...............( i )
2x + 3y = 1 .............. ( ii )
Now,multiply by 3 equation ( i) we get,
3 (3x + y ) = 5
9x + 3y = 15 .............( iii )
Subtract equation ( ii ) and (iii ) we get,
2x + 3y = 1
9x + 3y = 15
------------------
-7x = -14 .........(multiple by -1)
7x = 14
x = 14/7
x = 2
: x = 2 taking equation ( ii ) we get,
2x + 3y = 1
2 * 2 + 3y = 1
4 + 3y = 1
3y = 1-4
3y = -3
y = -3/3
y = -1
Therefore, x = 2 and y = -1 are the solution of the equation.
Thanks....
