ANSWER

2x+3y=8         ---------- ( 1 )             [ Given ]

2x=2+3y         --------- ( 2 )             [ Given ]

 

 x=22+3y           ----- ( 3 )

,substituting value of x in equation ( 1 ),

2(22+3y)+3y=8

2+3y+3y=8

2+6y=8

6y=8−2

6y=6

∴   y=1

substituting value of y=1 in equation ( 3 ),

x=22+3(1)

x=25

x=2.5
