\(\Leftrightarrow x=22\)

Answer 4

2x-36=3^2.2

2x-36=9.2

2x-36=18

2x     =18+36

2x     =54

 x      =54:2

 x      =27

Answer 5

=> 2x-26 = 9 x 2 = 18

=> 2x = 18 + 26 = 44

=> x = 44 : 2 = 22

Answer 6

An

2x - 26 =3².2

2x - 26 = 9.2

2x - 26 = 18

  2x      = 18 + 26

  2x      = 44

  x        =  44: 2

  x        =  22

Vậy x= 22

Answer 7

2x-26 = 3^2 x 2

2x-26 =18

2x=18+26

2x=44

x=44:2

x=22

Answer 8

\(2x-26=3^2.2\)

\(2x-26=18\)
