Tìm x, biết:
\(a,\dfrac{1}{3}:\left(2x-1\right)=\dfrac{-1}{6}\)
\(b,\left(3x+2\right)\left(\dfrac{-2}{5}x-7\right)=0\)
\(c,\dfrac{x}{8}=\dfrac{9}{4}\)
\(d,\dfrac{x-3}{2}=\dfrac{18}{x-3}\)
\(e,4,5x-6,2x=6,12\)
\(h,11,4-\left(x-3,4\right)=-16,2\)
Tìm x biết:
\(\left(2x+\frac{1}{3}\right)\left(\frac{3}{4}x-6\right)-\left(3x-\frac{2}{3}\right)\left(\frac{1}{2}x-\frac{6}{9}\right)=1\)
Tìm x biết:
\(a,\left(x-\dfrac{3}{4}\right)+50\%=\dfrac{1}{6}\)
\(b,\dfrac{1}{2}x-\dfrac{5}{6}x=\dfrac{7}{2}\)
\(c,\left(4-x\right)\left(3x+5\right)=0\)
\(d,\dfrac{x}{16}=\dfrac{50}{32}\)
\(e,\left(2x-3\right)+\dfrac{3}{2}=-\dfrac{1}{4}\)
Tìm số tự nhiên x , biết
\(2\cdot\left(x-1\right)^2=8\)
\(\left(2x+1\right)^3=125\)
\(\left(x-2\right)^5=243\)
\(5\left(x-4\right)^2-7=13\)
\(221-\left(3x+2\right)^3=96\)
\(x-14=3x+18;\)\(2.\left(x-5\right)-3\left(x-4\right)==-6+15.\left(-3\right);\)
\((x+7\left(\right).\left(x-9\right)=0\);\(|2x-5|-7=22\)
tìm x , biết
\(a,\left|2x-3\right|-\left|3x+2\right|=0\\ b,\left|\dfrac{1}{2}x\right|=3-2x\)
Tìm x thuộc Z biết
a) \(2.\left(x-3\right)-3.\left(x-5\right)=4.\left(3-x\right)-18\)
b) \(-2x-11\)chia hết cho \(3x+2\)
Tìm x biết:
\(a,18:(x-3)=6\)
\(b,\)\(3^{x-1}+4=85\)
\(c,2x+3x=55\)
\(\left(x-3\right)^3+11=53\)
Nhờ các bạn giúp mk nhé
\(2\left(X-5\right)-3\left(X-4\right)=\left(-6\right)+15\left(-3\right)\)
\(\left|X-1\right|+\left|X-5\right|=4\)
3X chia hết cho X-1 Tìm x
2X+7 chia hết cho X-3
tìm số nguyên x bt
1) \(1+x-2\left(5+3x\right)=4-5x\)
2)\(\left(2x-3\right)^3=-\left(-6^2\right)-\left(-2\right)^3+\left(-1\right)^{2011}\)
