Step-by-step explanation:
Given 2x+3y=8 ......... (1)
x+y=5 ........... (2)
From (1), we have x=
2
8−3y
............ (3)
From (2), we have x=5−2y .......... (4)
Now, comparing the value of x, we get
2
8−3y
=5−2y
or 8−3y=10−4y
or 4y−3y=10−8
or y=2
Using y=2 in (4), x=5−2×2=1.

2x+3y=8
2x=8-3y
x=8-3y/2
x+y=12
put the value of x
8-3y/2+y=12
8-3y/2+2y/2=12
8-y/2=12
8-y=12×2
8-y=24
-y=24-8
y=-16
now put the value of y
x=8-3×(-16)/2
x=8+48/2
x=56/2
x=28
here is answer
y is -16 and x is 26
