tim x biet 2x+1/x-2=2x-3/x+6
Tim X,
biet 4(18-5x)-12(3x7)=15(2x-16)-6(2+14)
tim x,y,z biet x/4=y/3 . x/3=z/5 và 2x-3y=6
Tim x biet: \(\frac{x+2}{2x-1}=\frac{x-6}{2x+3}\)
Tim x biet |x-3|-6=2x
Tim x,y,z biet x/4=y/3 . x/3=z/5 và 2x - 3y + z=6
Tim x biet:
a.2|2x-3|=1/2
b.(x-1)^2=9/16
c.3/5(x-5/6)-1/2(3/2-1)=-1/4
d.1/3+1/6+1/10+......+2/x(x+1)=2015/2016
tim x biet \(|6-2x|+|x-13|=0\)
|(x+1/2).|2x-3/4||=2x-3/4 tim x biet
