Giúp gấp cần gấp ạ e camo

`a ) (x+60) - 160 = 0`

`=> x + 60 = 0 + 160`

`=> x + 60 = 160`

`=> x = 160 - 60`

`=> x = 100`

Vậy `x = 100`

`b ) 156 - 9x+61 = 82`

`=> 156 - 9x = 82 - 61`

`=> 156 - 9x = 21`

`=> 9x = 156 - 21`

`=> 9x = 135`

`=> x = 135 : 9`

`=> x = 15`

Vậy `x = 15`

`c ) 12 : (3x - 7) + 34= 40`

`=> 12 : (3x - 7) = 40 - 34`

`=> 12 : (3x - 7) = 6`

`=> 3x - 7 = 12 : 6`

`=> 3x - 7 = 2`

`=> 3x = 2 +7`

`=> 3x = 9`

`=> x = 9:3`

`=> x = 3`

Vậy `x = 3`

`d ) 101 + (105 : x - 12) . 7 = 122`

`=> (105:x-12) . 7 = 122 - 101`

`=> (105 : x - 12) . 7 = 21`

`=> 105 : x - 12 = 21 : 7`

`=> 105 : x - 12 = 3`

`=> 105 : x = 3 + 12`

`=> 105 : x = 15`

`=> x = 105 : 15`

`=> x = 7`

Vậy `x = 7`

`e ) 12 . [43 - (56-x)] = 384`

`=> 43 - 56+ x= 384 : 12`

`=> -13 + x = 32`

`=> x = 32 - (-13)`

`=> x = 45`

Vậy `x = 45`

`f ) 26 - 3.(x-5) = 14`

`=> 3.(x-5) = 26 - 14`

`=> 3.(x-5) = 12`

`=> x-5 = 12:3`

`=> x -5 = 4`

`=> x = 4 +5`

`=> x = 9`

Vậy `x = 9`

`g ) 144 : (8x - 76) = 36`

`=> 8x - 76 = 144 : 36`

`=> 8x - 76 = 4`

`=> 8x = 4 +76`

`=> 8x = 80`

`=> x = 80 :8`

`=> x = 10`

Vậy `x = 10`

`h ) 7.(x-6) = 4x +9`

`=> 7x - 42 = 4x+9`

`=> 7x - 4x = 42+9`

`=> (7-4)x = 51`

`=> 3x = 51`

`=> x = 51 : 3`

`=> x = 17`

Vậy `x = 17`
