3x-2y=5.....3
multiplying both sides by 3 we get
9x-6y=15.......1
3y-2x=3.........4
multiplying both sides by 2, we get
6y-4x=6........2
adding 1 and 2 we get
9x-6y+6y-4x=21
5x=12
x=21/5
then
x+t=12/5+t
if u have to find x+y then
adding 3 and 4 we have
3x-2y+3y-2x=8
x+y=8
multiplying both sides by 3 we get
9x-6y=15.......1
3y-2x=3.........4
multiplying both sides by 2, we get
6y-4x=6........2
adding 1 and 2 we get
9x-6y+6y-4x=21
5x=12
x=21/5
then
x+t=12/5+t
if u have to find x+y then
adding 3 and 4 we have
3x-2y+3y-2x=8
x+y=8
