`648 - 34*x = 444`
`=> 34x = 648 - 444`
`=> 34x = 204`
`=> x = 204 \div 34`
`=> x = 6`
Vậy, `x = 6.`
Lời giải:
$648-34x=444$
$34x=648-444=204$
$x=204:34=6$

648 - 34 . x = 444
34 . x = 648 - 444
34 . x = 204
x = 204 : 34
x = 6
Đúng nha !!!!!
648 - 34 . x = 444
34 . x = 648 - 444
34 . x = 204
x = 204 : 34
x = 6

648 - 34 . x = 444
34 . x = 648 - 444
34 . x = 204
x = 204 : 34
x = 6
Chúc bạn học thật giỏi nha !!!

x = 204 : 34
x = 6
b) 1482 : x + 23 = 80
1482 : x = 80 - 23
1482 : x = 57
