Giúp em với hứa cho ctlhn ạ

`a ) 17x + 33x = 100`

`( 17 + 33 )x = 100`

`50x = 100`

    `x = 100 : 50`

    `x = 2`

`b ) 23x + 15( x + 7 ) = 105`

`23x + 15x + 15 . 7 = 105`

`( 23 + 15 )x + 105 = 105`

`38x = 105 - 105`

`38x = 0`

   `x = 0 : 38`

   `x = 0`

`c ) 32(x - 11 ) + 4x = 152`

`32x - 32 . 11 + 4x = 152`

`( 32 + 4 )x - 352 = 152`

`36x = 152 + 352`

`36x = 504`

    `x = 504 : 36`

     `x = 14`

`d ) 51( 3x + 5 ) - 406 = 22(3x + 5 )`

`51 . 3x + 51.5 - 406 = 22.3.x + 22.5`

`153x + 255 - 406 = 66. x + 110`

`153x - ( 406 - 255 ) = 66.x + 110`

`153x - 151 = 66x + 110`

`153x - 151 + 151 = 66x + 110 + 151`

`153x = 66x + 261`

`153x - 66x = 261`

`( 153 - 66 )x = 261`

`87x = 261`

    `x = 261 : 87`

     `x = 3`
