\(2\frac{2}{4}-x=1\frac{2}{4}\)
\(x=2\frac{2}{4}-1\frac{2}{4}\)
\(x=1\)
\(\frac{5}{2}\)-x=\(\frac{3}{2}\)
x=\(\frac{5}{2}-\frac{3}{2}\)
x=1
k mk nha!
Tìm x
a \(\frac{3}{4}+\frac{1}{4}xX=2\)
b X - \(\frac{2}{3}x\frac{9}{4}=2,5-\frac{1}{2}\)
c \(2xX+\frac{1}{3}=\frac{4}{3}\)
d \(X:\frac{2}{3}+0,75=\frac{9}{4}+3\)
e \(\frac{6}{4}:X+\frac{1}{2}=\frac{9}{4}x\frac{2}{3}\)
f \(Xx\frac{3}{5}-\frac{2}{5}=3\frac{3}{4}-1\)
tìm x:
a) \(\frac{7}{4}-x+.\frac{4}{3}=\frac{5}{19}\) b) \(x.\frac{1}{2}+\frac{3}{2}.x=\frac{4}{5}\)
bài 1: tìm x:
a) \(x\cdot\frac{7}{9}=\frac{2}{3}+2\frac{1}{2}\) b) \(\frac{5}{7}+x:\frac{9}{4}=\frac{4}{3}\)
Bài 1 : Tìm x
a, \(\frac{1}{2}+x+1\frac{1}{2}=3\frac{3}{4}\)
b, \(\frac{5}{6}\div x-\frac{4}{9}=\frac{3}{4}\)
Tìm x:\(\left(x-\frac{1}{2}\right)\times\frac{5}{2}+\frac{1}{2}=\frac{7}{4}\)
Tìm x trong biểu thức sau
\(\left(3\frac{3}{4}:\frac{1}{4}-2\frac{2}{5}\cdot1\frac{1}{4}\right)-\left(3\frac{1}{2}:2,5-\frac{1}{5}\right)-\frac{1}{5}\cdot x=\frac{51}{5}\)
Tìm \(x\):
a)\(x\) x \(3\frac{1}{3}=3\frac{1}{3}:4\frac{1}{4}\)
b)\(5\frac{2}{3}:x=3\frac{2}{3}-2\frac{1}{2}\)
c)\(\frac{x-1}{49}+\frac{x-2}{48}+\frac{x-3}{47}+\frac{x-4}{46}+\frac{x-5}{45}-5=0\)
Tìm x
\(\frac{4}{3}+x\cdot\frac{2}{3}-\frac{1}{4}=4\frac{5}{12}\)
Tìm X biết
a) \(x\cdot\frac{2}{7}\cdot\frac{3}{4}=\frac{5}{21}\)
b) \(x\cdot\frac{1}{2}=\frac{1}{3}\)
