Question

12x-33=243

Answer 1

12x - 33 = 243

12x = 243 + 33

12x = 278

x = 278 : 12

x = 24

Answer 2

12x-33=243

<=> 12x= 243-33= 210

<=> x= 210:12

<=> x= 17,5

Answer 3

12 x - 33 = 243

12 x        = 243 + 33

12 x        = 276

     x        = 23

Answer 4

12x - 33 = 243

12x = 243 + 33

12x = 276

x = 276 : 12

x = 23

vậy số đó là 23

Answer 5

12x-33=243

12x    = 243+33

12x    = 276

   x    = 276:12

   x    = 23
