Given: x−2x+2−163x+5=3−72x
⇒x−2x−16x3+7x2=3−2−5
⇒6x−12x−32x+21x6=−4
⇒−17x6=−4
⇒−17x=−4×6
⇒−17x=−24
⇒x=−24−17
⇒x=2417
To check: x−2x+2−163x+5=3−72x
for x=2417
L.H.S=x−2x+2−163x+5
=2417−2(2417)+2−(163)(2417)+5
=2417−4817+2−12817+5
=24−48+34−128+8517
=−3317
R.H.S=3−72x
=3−(72)(2417)
=3−16834
=102−16834
=−6634
=−3317
∴L.H.S=R.H.S
Hence, the given equation is verified for x=2417.
