4X=(X+Y-X)/3
4X=(130-X)/3
12X=130-X
13X=130
X=130/13=10
X+Y=130
10+Y=130
Y=120
4X=(X+Y-X)/3
4*10=(10+120-10) /3
40=120/3
40=40
Therefore,L.H.S=R.H.S

X + y = 130
X= 130 - y
4x = ( x + y - x ) / 3put the value of x in this eq
4(130- y) = y/3
12(130 - y ) = y
1560 - 12 y = y
13 y = 1560
Y = 120 ans
Put this value in 1st eq
X + 120 = 130
And we get x= 10
4x = ( x+ y - x ) / 3
4× 10 = 120 / 3
40 = 40
