\(\left(4,5-2x\right).\frac{11}{7}=\frac{11}{14}\)
\(4,5-2x=\frac{11}{14}.\frac{7}{11}=\frac{1}{2}\)
\(2x=\frac{1}{2}-4,5=-4\)
\(x=\left(-4\right):2=-2\)
Tìm x biết
\(2\frac{x}{7}=\frac{75}{35}\)
\(\left(4,5-2x\right).\frac{14}{7}=\frac{11}{4}\)
Tìm x biết
\(a,\left[20\%x+\frac{2}{5}x-2\right]\div\frac{1}{3}=2013\)
\(b,\left[4,5-2\left|x\right|\right]\times1\frac{4}{7}=\frac{11}{14}\)
Tìm x, biết :
\(\left(2,8x-32\right)\div\frac{2}{3}=-90\)
\(\left(4,5-2x\right)\times1\frac{4}{7}=\frac{11}{14}\)
\(\left(4,5-2.x\right).1\frac{4}{7}=\frac{11}{14}\)
tìm x
\(|x+3|\div\left(-15\right)=\frac{1}{3}\)
\(|4,5-2x|\cdot(-1\frac{4}{7})=\frac{-11}{14}\)
giúp mình với mai mình nộp rồi
Tìm x:
a, x + 30%x = -1,31
b,\(\left(x-\frac{1}{2}\right):\frac{1}{3}+\frac{5}{7}=9\frac{5}{7}\)
c, \(\frac{1}{2}x-\frac{3}{4}=\frac{14}{9}.\frac{3}{7}\)
d,\(\frac{-5}{6}-x=\frac{7}{12}+\frac{-1}{3}\)
e,\(\frac{x+3}{-15}=\frac{1}{3}\)
f,\(\left(4,5-2x\right).\left(-1\frac{4}{7}\right)=\frac{11}{14}\)
