MÌNH ĐANG CẦN GẤP GIẢI CỤ THỂ GIÚP MÌNH NHA
Tìm x:
|5x-3|-3x=7
|x-3|+|x-5|-4x=-28
\(\left|x+2\right|+\left|x+\frac{3}{5}\right|+\left|x+\frac{1}{2}\right|=4x\)
\(\left|2x-1\right|+\left(4x^2-1\right)^2=0\)
a. \(\frac{2-x}{4}=\frac{x+1}{-3}\)

a)\(\left|x-3\right|=x+4\)
Tìm x biết
1) \(\left(2x+3\right)\left(x-4\right)+\left(x-5\right)\left(x-2\right)=\left(3x-5\right)\left(x-4\right)\)
2)\(\left(8x-3\right)\left(3x+2\right)-\left(4x+7\right)\left(x+4\right)=\left(2x+1\right)\left(5x+1\right)-33\)
3)\(6x\left(3x+5\right)-2x\left(9x-2\right)+\left(17-x\right)\left(x-1\right)+x\left(x-18\right)-17x^2=0\)
4)\(\left(x-1\right)\left(x+2\right)-\left(x-3\right)+5x-7=0\)
Giúp mình nha. Camon nhiều
Bài 1:Tìm x
a)\(\left(5x+1\right)^2=\frac{36}{49}\)
b)\(\left(x-\frac{2}{9}\right)^3=\left(\frac{2}{3}\right)^6\)
c)\(\left(8x-1\right)^{2x+1}=5^{2x+1}\)
tìm x
1 , \(\left|\frac{3}{2}x-1\right|-2x=1\)
2, | 7 - 2x | + 7 = 2x
3 , | 5x - 2 | +2 = 5x
4 , \(\left|x\left(x^2-\frac{5}{4}\right)\right|=x\)
