các bạn giải nhanh giúp mình nhé
2448:[119-(x-6)]=24
`2448:[119-(x-6)]=24`
`=>119-(x-6)= 2448 : 24`
`=>119-(x-6)= 102`
`=> x-6=119-102`
`=> x-6=17`
`=>x=17+6`
`=>x=23`
`2448:[119-(x-6)]=24`
`=>119-(x-6)= 2448 : 24`
`=>119-(x-6)= 102`
`=> x-6=119-102`
`=> x-6=17`
`=>x=17+6`
`=>x=23`
2448 : {119- [X - 6] }=24
2448 : 24=102
119-102=17
17+6=23
x=23
2448:[119.(x-6)]=24
\(2448:\left[119.\left(x-6\right)\right]=24\)
\(119.\left(x-6\right)=2448:24=102\)
\(x-6=102:119\)
=> sai de
2448:[119-(x-6)]=24
2448 : [ 119 - ( x - 6 )] = 24
119 - ( x - 6 ) = 2448 : 24
119 - ( x - 6 ) = 102
x - 6 = 119 - 102
x - 6 = 17
x = 17 + 6
x = 23
Mình chưa chắc đúng đâu bạn nhé!!!
\(2448:\left[119-\left(x-6\right)\right]=24\)
\(119-\left(x-6\right)=2448:24\)
\(119-\left(x-6\right)=102\)
\(x-6=119-102\)
\(x-6=17\)
\(x=17+6\)
\(x=23\)
\(2448:\left[119-\left(x-6\right)\right]=24\)
\(119-\left(x-6\right)=102\)
\(x-6=17\)
\(x=23\)
