Question

12x - 3x +1= 937

tìm x 

Answer 1

x.(12-3)+1=937

x.9+1=937

x.9=937-1

x.9=936

x=935:9

x=104

Answer 2

12x - 3x + 1 = 937

(12 - 3).x + 1 = 937

9 . x + 1 = 937

9 . x       = 937 - 1

9 . x       = 936

    x        = 936 : 9

    x        = 104

Answer 3

12x -3x +1 =937 

12x-3x= 937-1 = 936

3x (4-1)= 936

3x = 936/ 3=312

x= 312/3=104
