a.1+2+3+4+....+x=1275
b.\(\frac{1}{3}+\frac{1}{15}+\frac{1}{35}+....+\frac{1}{x\cdot\left(x+2\right)}\)
bài 1: tìm x:
a) \(x\cdot\frac{7}{9}=\frac{2}{3}+2\frac{1}{2}\) b) \(\frac{5}{7}+x:\frac{9}{4}=\frac{4}{3}\)
tìm x , biết:
\(x+1\frac{1}{2}=\frac{3}{2}+\frac{1}{2}\)
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 :
\(1\frac{2}{3}+x=2\frac{1}{3}\)
