Tìm x, biết: \(\frac{2x-1}{-27}=\frac{3}{1-2x}\)
Tìm x
\(a,\left(3\frac{1}{2}-2x\right).1\frac{1}{3}=7\frac{1}{3}\)
\(b,\frac{-2}{9}|4\frac{1}{5}x-1\frac{1}{2}|=\frac{-4}{27}\)
Bài 8: Tìm số nguyên x biết
a) \(\left(\frac{-12}{27}+\frac{2}{3}\right)+\frac{-2}{9}\le x\le\left(\frac{11}{7}+\frac{2}{5}\right)+\frac{7}{5}+\frac{3}{7}\) b\(\frac{-x}{2}+\frac{2x}{3}+\frac{x+1}{4}+\frac{2x+1}{6}=\frac{8}{3}\)
c)\(\frac{3}{2x+1}+\frac{10}{4x+2}-\frac{6}{6x+3}=\frac{12}{26}\)
Tìm x nếu
\(a,3^4:3^x=27\)
\(b,4^x.\frac{1}{3}+4^x.3=\frac{5}{3}.2^7\)
\(c,2^x.\frac{1}{4}+2.2^x=9.2^6\)
\(d,\left(8x-1\right)^{2x+1}=7^{2x+1}\)
Tìm x : \(\frac{2x-3}{3}\)= \(\frac{27}{2x-3}\)
tìm x
\((2x-\frac{1}{3})^2=\frac{-1}{27}\)
