x + 4 + 24 / 6 = 78
x + 4 + 4 = 78
x = 78 - 4 - 4
x = 70
x + 4 + 24 : 6 = 78
=> x + 4 + 24 = 78 x 6=468
=> x + 4 = 468 -24 = 444
=> x = 444-4 = 440
x + 4 + 24 : 6 = 78
x + 4 + 24 = 78 x 6
x + 4 + 24 = 468
x + 4 = 468 - 24
x + 4 = 444
x = 444 - 4
x = 440
Vậy x = 440
x + 4 + 6 = 78
x = 78 - 6 - 4
x = 68
x+4+24:6=78
x+4+4=78
x+4=78-4
x+4=74
x=74-4
x=70
vậy x=70
x + 4 + 24 : 6 = 78
x + 4 + 24 = 78 x 6
x + 4 = 468 - 24
x + 4 = 444
x = 444 - 4
x = 440
Vậy x = 440
x + 4 + 24 : 6 = 78
x + 4 + 24 = 78 x 6
x + 4 = 468 - 24
x + 4 = 444
x = 444 - 4
x = 440
Vậy x = 440
x + 4 + 24 : 6 = 78
x + 4 + 24 = 78 x 6
x + 4 = 468 - 24
x + 4 = 444
x = 444 - 4
x = 440
Vậy x = 440
Ta có :
x + 4 + 24 : 6 = 78
x + 4 + 24 = 78 x 6
x + 4 = 468 - 24
x + 4 = 444
x = 444 - 4
x = 440
Vậy x = 440
Ta có :
x + 4 + 24 : 6 = 78
x + 4 + 24 = 78 x 6
x + 4 = 468 - 24
x + 4 = 444
x = 444 - 4
x = 440
Vậy x = 440
