\(\left|3x+8\right|=\left|2-x\right|\)
TH1: \(3x+8=-\left(2-x\right)\)
=>\(3x+8=x-2\)
=>\(2x=-10\)
=>\(x=-5\)
TH2: \(3x+8=2-x\)
=>\(4x=-6\)
=>\(x=-\frac{3}{2}\)
Vậy .................
tim x,y,z biet 3x/8=3y/64=3z/216va 2x^2+2y^2-z^2=1
tim x biet :
a) |x+1| +|x-5| = 7
b)|2x + 5|=3x-8
cho x/4=y/5.tim x y biet a) x+y=54 b) 3x -2y=8 c) x.y=80
tim x biet
|x+1|+|3x+2|=3x
|x-2|+4|x+1|=x-3
tim x biet /x^2+/3x-1//=x^2+7
tim x biet |3x-2|-x=7
tim x biet : 2^3x+2 = 4^x+5
tim x biet /3x-2/-x>1
Tim x,y,z biet: a,(3x−2y)6+(y−5z)8+|z−2|=0(3x−2y)6+(y−5z)8+|z−2|=0
b,3x−2y4=2x−4z3=y−3z23x−2y4=2x−4z3=y−3z2va x+y+z=990
