listen bro
exam ka question he ye
x+y=30 ....(i)
x-y=14.....(ii)
now
x=14+y.....(iii)
so,
on substituting the value of x in equation i, we get
14+y+y=30
14+2y=30
2y=16
y=8
now, x-y=14
so,. x=14+8=22


hope this helps you

Hii friend......
x+y = 30------> (i)
x-y = 14 -------(ii)
_________________________________________Using Substitution method :
x+y = 30
x= 30-y-----(iii)

Putting x = 30- y in equation (ii).
x-y = 14
30-y-y = 14
30-2y = 14
-2y = 14-30
-2y = -16
y = 8

Putting y = 8 in equation (iii)
x= 30-8
x= 22
so, x= 22 & y = 8

THANKS
HOPE IT HELPS U☆☆☆
