72 – (4x + 24) = 936

Answer 1

72 – (4x + 24) = 936

        4x+24=936-72

        4x+24=864

        4x      =864-24

        4x      =    840

          x      =    840:4

          x      =      210.

Vậy x=210.

Answer 2

4x + 24 = 72 - 936

4x + 24 = -864

4x         = -864 - 24

4x         = -888

  x         = -888 : 4

  x         = -222

Answer 3

72 - (4x+24)=936

4x+24=72-936

4x+24=-864

4x =-864-24

4x=-888

x=-888:4

x=-222
