\(\frac{75}{2}-\frac{1}{50}.\left(\frac{2}{3}x-1\right)^3=24\)
Tìm x
Tìm tập hợp số nguyên x biết :
a) \(\frac{1}{2}-\left(\frac{1}{3}+\frac{1}{4}\right)
a) Tìm x biết:
\(\left(x-\frac{2}{5}\right).\left(x+\frac{3}{7}\right)
Tìm x, biết
A.\(\left(-1\frac{1}{5}+x\right):\left(-3\frac{3}{5}\right)=-\frac{7}{4}+\frac{1}{4}:\frac{11}{8}\)
B.\(7,5x:\left(5\frac{195}{315}-8\right)=2\frac{13}{15}\)
C.\(60\%x+\frac{2}{3}x+x=688\)
D.\(1-\left(5\frac{3}{8}-x-7\frac{5}{24}\right):16\frac{2}{3}=0\)
Tìm số nguyên x thuộc z biết:
a) \(\frac{1}{2}-\left(\frac{3}{3}+\frac{4}{4}\right)\le x\le\frac{2}{24}-\left(\frac{1}{8}-\frac{3}{3}\right)\)
b) \(\frac{1}{2}-\frac{1}{6}\le\frac{x-2}{3}\le\frac{1}{3}-\frac{1}{2}-\frac{3}{4}\)
tìm x, biết
a) |x+1|+|x+2|+|x+3|+...+|x+99|=100x
b) \(\left|x+\frac{1}{1.2}\right|+\left|x+\frac{1}{2.3}\right|+...+\left|x+\frac{1}{49.50}\right|=50.x\)
Bài 1 : Tìm x biết :
a, \(\left|\frac{3}{2}x+\frac{1}{2}\right|=\left|4x-1\right|\)
b, \(\left|\frac{5}{4}x-\frac{7}{2}\right|-\left|\frac{5}{8}x+\frac{3}{5}\right|=0\)
c,\(\left|\frac{7}{5}x+\frac{2}{3}\right|=\left|\frac{4}{3}x-\frac{1}{4}\right|\)
Bài 2 : Tìm x biết :
a, | 2x - 5 | = x +1
b, | 3x - 2 | -1 = x
c, | 3x - 7 | = 2x + 1
d, | 2x-1 | +1 = x
tìm x biết
\(\frac{\left(x-1\right)^2}{3}=\frac{24}{2}\)
TÌM X BIẾT
\(\frac{2.\left(\frac{-1}{2}\right).\left(\frac{2}{3}\right)^2-3\left(-\frac{1}{3}\right)^2.\frac{2}{9}:x}{3.\left(-\frac{1}{2}\right)-\frac{2}{3}}=1\)
