Question

solve the following equations and verify your answer 1) 2x+7=3(x+1) 2) 4x-11=7x-20​

Answer 1

Answer:

answer for the given problem is given

Answer 2

Answer:

1) 2x+7=3(x+1)⇒2x+7=3x+3

                      ⇒x=4

verification

2x+7=2×4+ 7 and    3( x+1)=3(4+1)

       =8 +7                            =3×5

       =15                                 =15

∴2x+7=3(x+1)

2) 4x-11=7x-20

⇒3x=9

⇒x =3

verification

4x-11=4×3-11     and   7x-20=7×3-20

       =12-11                            =21-20

        =1                                  =1

   ∴4x-11=7x-20
