\(\left(2x-2^4\right).6^3=2.6^4\)
\(\Rightarrow2x-2^4=2.6^4:6^3\)
\(\Rightarrow2x-2^4=2.6=12\)
\(\Rightarrow2x=12+16=28\)
\(\Rightarrow x=28:2=14\)
giup mik voi tim x biet
1, 5-(3x+6)>-2x+1
2, -7.(x+2)-3x<6-11x
3, (x+1).(x+2)-x.(x+3)<4-x
4, 6-2x>17+(4-x)
Tim x biet: (\(2x^2+7\))x(\(-3x-9\))<\(0\)
Giup mik voi ai nhanh mik tik cho^-^
Nho lam day du ho mik nhe,Thanks=))
Ai dang hoc lop 6 doi tuyen thi kb voi mk nhe
khi nao co bai ko hieu mik can hoi lam

GIUP MIK NHA CAC BAN MIK DANG CAN GAP LAM DAY CAC BAN IU
Tim x, biet:
1) -5.(2-x)+4.(x-3)=10.x-15
2) 2.(7x-14)-7.(3x-5)=28
3) 17+x=7+6.x
4) 4.!x-2!=8
5) 4.x-5.(-3+x)=7
mik dag gap lam tra loi nhanh va chi tiet giup mik
