Verified by Toppr

Given 

212x+8=x+6

⇒212x+168=x+6

⇒2x+168=21(x+6)

⇒2x+168=21x+126

⇒168−126=21x−2x

⇒19x=42

⇒x=1942.

Now, to verify Put x=1942in given equation.

L.H.S.= 2121942+8

R.H.S.=1942+6

by simplifying we get,

L.H.S.=R.H.S.

∴ it is verified that x=19/42is solution of given equation.
