Step-by-step explanation:

Correct option is

Correct option isA

Correct option isA64

Correct option isA64Given,

Correct option isA64Given,3

Correct option isA64Given,3 x+1

Correct option isA64Given,3 x+1 =9

Correct option isA64Given,3 x+1 =9 x−2

Correct option isA64Given,3 x+1 =9 x−2

Correct option isA64Given,3 x+1 =9 x−2 ⇒3

Correct option isA64Given,3 x+1 =9 x−2 ⇒3 x+1

Correct option isA64Given,3 x+1 =9 x−2 ⇒3 x+1 =3

Correct option isA64Given,3 x+1 =9 x−2 ⇒3 x+1 =3 2x−4

Correct option isA64Given,3 x+1 =9 x−2 ⇒3 x+1 =3 2x−4

Correct option isA64Given,3 x+1 =9 x−2 ⇒3 x+1 =3 2x−4 By comparing powers

Correct option isA64Given,3 x+1 =9 x−2 ⇒3 x+1 =3 2x−4 By comparing powersx+1=2x−4

Correct option isA64Given,3 x+1 =9 x−2 ⇒3 x+1 =3 2x−4 By comparing powersx+1=2x−4∴x=5

Correct option isA64Given,3 x+1 =9 x−2 ⇒3 x+1 =3 2x−4 By comparing powersx+1=2x−4∴x=5Now 2

Correct option isA64Given,3 x+1 =9 x−2 ⇒3 x+1 =3 2x−4 By comparing powersx+1=2x−4∴x=5Now 2 1+x

Correct option isA64Given,3 x+1 =9 x−2 ⇒3 x+1 =3 2x−4 By comparing powersx+1=2x−4∴x=5Now 2 1+x

Correct option isA64Given,3 x+1 =9 x−2 ⇒3 x+1 =3 2x−4 By comparing powersx+1=2x−4∴x=5Now 2 1+x =2

Correct option isA64Given,3 x+1 =9 x−2 ⇒3 x+1 =3 2x−4 By comparing powersx+1=2x−4∴x=5Now 2 1+x =2 1+5

Correct option isA64Given,3 x+1 =9 x−2 ⇒3 x+1 =3 2x−4 By comparing powersx+1=2x−4∴x=5Now 2 1+x =2 1+5

Correct option isA64Given,3 x+1 =9 x−2 ⇒3 x+1 =3 2x−4 By comparing powersx+1=2x−4∴x=5Now 2 1+x =2 1+5 =64
