\(\left|x+\dfrac{1}{2}\right|-6=-2\)
\(\left|x+\dfrac{1}{2}\right|=-2+6=4\)
\(\Leftrightarrow\left[{}\begin{matrix}x+\dfrac{1}{2}=4\\x+\dfrac{1}{2}=-4\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}x=4-\dfrac{1}{2}=\dfrac{7}{2}\\x=-4-\dfrac{1}{2}=-\dfrac{9}{2}\end{matrix}\right.\)
tìm x
a, 3/4 + -1/2x = 1
b, 1/6 :x -1/3 = 1/2
c,(x+1/5)2=9
d,22/9-(x+1/2)2=7/3
e, 2|x|+1/2=2
f,|x+1/2|-1/6=1
giải giúp mình vs mk đang cần gấp
A) (x-2)^2=1/16
B) (x-1)^2=(1-x)^4
C) (3x-1/5)^2=(2/3)^6
Đ) 3x/27=3^-1
rút gọn biểu thức P= 1/2-1/2*(x:1/6-1/4)-2|3x-2| khi.:
a, x>= 2/3.
b, x< 2/3
giúp mik với:
a,|2x-3|- 1/2=3/4
b,|-1,2|+5,8-|x|=/4,3/
c,|x+3/5|- 2/3=1/6
d,3.|3/2 +x|=6
|x/2-2/3|-1/2=5/6
Tim x,biet:
5:6-1:2×(x-1:3)-2:5×x=0
x+1/2 + x+3/3 +x+1/4 = x+1/5 + x+1/6
