hey mate this is ur ans hope it
helps u!!!!!
let us take
2x+3y=5..............(i)
3x+2y=10............(ii)
by elimination method we can solve it so let us take
3(2x+3y=5) ......1
2(3x+2y=10)..........2
1st eq will be
6x+9y=15
2nd eq will be
6x+ 4y=20
now by elimination method
6x+9y=15
6x+4y=20
.
.. = 5y= - 5
y= - 1
and hence x will be
by 1st eq
2x-3=5
2x=8
x=4
-----------------------------—-------------------------------------------------------
check
value of x and y as 4 and - 1
2.4+3.-1
8-3=5
lhs=rhs
3.4+(-2)
12-2
10 hence lhs =rhs
therefore our solution is correct
