\(\hept{\begin{cases}\text{|}0,5x\text{|}=0,5x\\\sqrt{\left(0,5x\right)^2}=0,5x\\\left(0,5x\right)^2=\left(0,5x\right)^2\end{cases}}\)
2, tương tự
\(\hept{\begin{cases}\text{|}-\frac{2}{3}x\text{|}=\frac{2}{3}x\\\sqrt{\left(-\frac{2}{3}x\right)^2}=\frac{2}{3}x\\\left(-\frac{2}{3}x\right)^2=\left(\frac{2}{3}x\right)^2\end{cases}}\)
4, tương tự
\(\frac{2}{3}-1\frac{4}{15}x=\frac{-3}{5}\)
-23+0,5x=1,5
Tìm x,biết:
a)\(\frac{4}{7}-x=\frac{1}{3}\)
b)|x-5|=7
c)\(x-\frac{2}{3}=\frac{-6}{7}\)
d)\(\frac{x}{3}=\frac{8}{12}\)
e)\(\frac{2}{3}-1\frac{4}{15}x=\frac{-3}{5}\)
f)\(-2^3+0,5x=1,5\)
g)\(2^{x-1}=16\)
Help!!
Tìm x , biết :
\(a,\frac{x+1}{2x+1}=\frac{0,5x+2}{x+3}\)
Tìm x
a, \(-\frac{22}{15}x+\frac{1}{3}=\text{|}-\frac{2}{3}+\frac{1}{5}\text{|}\)
b,\(x:15=8:24\)
c,\(\frac{-3x+2}{5x+7}=\frac{3x-1}{5x+1}\)
d, \(\frac{x+1}{2x+1}=\frac{0,5x+2}{x+3}\)
nói cách làm lun nha
tim x biet
a;\(\frac{3x+2}{5x+7}=\frac{3x-1}{5x+1}\)
b; \(\frac{x+1}{2x+1}=\frac{0,5x+2}{x+3}\)
Tìm x biết \(\frac{x+1}{2x+1}=\frac{0,5x+2}{x+3}\)
Tìm x biết :
a, \(\left|0,5x-2\right|-\left|x+\frac{1}{3}\right|=0\)
b, \(2x-\left|x+1\right|=\frac{1}{2}\)
c, \(\left|2x-1\right|-\left|x+\frac{1}{3}\right|=0\)
d, \(3x-\left|x+15\right|=\frac{5}{4}\)
Tìm x :
a) \(\frac{3x+2}{-4x+5}\)=\(\frac{-4}{3}\) c) \(\frac{\left(2x+1\right)}{5}=\frac{3}{2x-1}\) e)\(\frac{\left|6x+1\right|}{4}=\frac{2}{4}\)
b) \(\frac{2.\left|x\right|+5}{-4x+3}\)=\(\frac{-5}{4}\) d)\(\frac{x+1}{2x+1}=\frac{0,5x+2}{x+3}\) g) \(\frac{\left|3x-5\right|}{3}=\frac{2\left|x\right|}{4}\)
P/S : HuHU T_T Giúp mk với T_T 1 câu thôi cx đc T_T AI giúp mk sẽ tik 6 tik nhé ^^ Thanks mng trước ạ T_T
