12x-33=9.27
12x-33=243
12x=243+33
12x=276
x=276:12
x=23
12 x- 33= 3^2 . 3^3
12 x- 33= 3^5
12 x- 33=243
12 x =243+ 33
12 x = 276
x =276:12
x = 23
Vậy x = 23
12x - 33 = 9 . 27
12x - 33 = 243
12x = 243 + 33
12x = 276
x = 276 : 12
x = 23
Vậy x = 23
k nha
Tìm x
12x - 33 =32.33
12x - 33 =243
12x = 243+33
12x = 276
x=276 : 12
x=23
Vậy x = 23
