Giải thích các bước giải:
`1)`
`16-(x+5)=14`
`=>x+5=16-14`
`=>x+5=2`
`=>x=2-5`
`=>x=-3`
Vậy `x=-3`
`2)`
`5x-(x-2)=12-(-x)`
`=>5x-x+2=12+x`
`=>5x-x-x=12-2`
`=>x.(5-1-1)=10`
`=>x.3=10`
`=>x=10:3`
`=>x=10/3`
Vậy `x=10/3`
`3)`
`3-(17-x)=783-(36+783)`
`=>3-(17-x)=783-36-783`
`=>3-(17-x)=(783-783)-36`
`=>3-(17-x)=-36`
`=>17-x=3+36`
`=>17-x=39`
`=>x=17-39`
`=>x=-22`
Vậy `x=-22`
`4) `
`2448:[103−(x−6)]=24`
`=>103-(x-6)=2448:24`
`=>103-(x-6)=102`
`=>x-6=103-102`
`=>x-6=1`
`=>x=1+6`
`=>x=7`
Vậy `x=7`
