tim x biet :
a. 3x+4 _>7
b. -5x+1<11
c. \(\frac{5}{x-3}\)< 0
d. \(\frac{-7}{2-x}\)> 0
giup mk voi ai bit thi giup mk tick
1 tim x \(2014.\left|x-12\right|+\left(x-12\right)^2=2013.\left|12-x\right|\)\(x\)|
2 chung minh \(8^7-2^{18}⋮14\)
3 tim x,y,z biet 4x=7y=3z va x+y+z=61
4 tim a,b,c biet \(\frac{1}{2}a=\frac{2}{3}b=\frac{3}{4}c\)vs \(a-b=15\)
giup mk nha moi nguoi,lm dc cang nhiu cang tot
giup minh nha mai minh nop roi ^_^ ^_^
\(\frac{x-1}{2}=\frac{y-2}{3}=\frac{z-3}{4}vax-2y+3z=14\)
de bai la tim x, y, z biet
giup mk
mk tk
mk dag voi
tim: x,y,z biet: x/7 = y/11 = z/13 = 0,(946053)
[ma (946053) la chu ki do nha]
Tim x biet x^3 =x
Giup minh voi thanks trc nha
1) Tim x, biet:
a) /2-x / =1/2
b) 3- / x +1/2 / = 1
c) / x - 1/2 / < 3
d) / x + 2 / > 1
tat ca deu la bai lien quan den gia tri tuyet doi nha may ban
giup mk nha
tim x biet
|3x+9| + 3|x-1|=12-|x+1|20
giup mk voi mk danh dau cho
