\(x.\frac{1}{2}=2\) ; \(x+2=\frac{1}{2}+\frac{1}{2}\)
\(x=2:\frac{1}{2}\) \(x+2=\frac{2}{4}\)
\(x=4\) \(x=\frac{2}{4}-2\)
\(x=\frac{-6}{4}\)
\(x.\frac{1}{2}=2\)
\(x=2:\frac{1}{2}\)
\(x=4\)
\(x+2=\frac{1}{2}+\frac{1}{2}\)
\(x+2=1\)
\(x=1-2\)

x+\(\frac{1}{2}\)=\(\frac{1}{4}\)+\(\frac{2}{4}\)
x+\(\frac{1}{2}\)=\(\frac{3}{4}\)
x=\(\frac{3}{4}\)-\(\frac{1}{2}\)
x=\(\frac{1}{4}\)
x+\(\frac{1}{2}\)=\(\frac{1}{4}\)+\(\frac{2}{4}\)
x+\(\frac{1}{2}\)=\(\frac{3}{4}\)
x=\(\frac{3}{4}\)-\(\frac{1}{2}\)

\(x.\frac{1}{2}=\frac{1}{2}+\frac{2}{4}\)
\(x.\frac{1}{2}=\frac{3}{4}\)
\(x=\frac{3}{4}:\frac{1}{2}\)
\(x=\frac{3}{2}\)
\(\left(1-\frac{2}{5}\right)\times\left(1-\frac{2}{7}\right)\times\left(1-\frac{2}{9}\right)\times\left(1-\frac{2}{11}\right)\times\left(1-\frac{2}{13}\right)\)
\(=\frac{3}{5}\times\frac{5}{7}\times\frac{7}{9}\times\frac{9}{11}\times\frac{11}{13}=\frac{3}{13}\)
\(x-\frac{1}{2}=\frac{2}{4}+\frac{1}{2}\)
\(x-\frac{1}{2}=1\)
\(x=1+\frac{1}{2}\)
\(x=\frac{3}{2}\)
\(x-\frac{1}{2}=1+\frac{2}{1}\)
\(x-\frac{1}{2}=3\)
\(x=3+\frac{1}{2}\)
\(x=\frac{7}{2}\)
x- 1/2= 1+2/1
=>x-1/2=1+2
=>x-1/2=3
=>x=3+1/2
=>x=6/2+1/2
=>x=7/2
\(x+1\frac{1}{2}=2\frac{1}{2}\)
\(x=2\frac{1}{2}-1\frac{1}{2}\)
\(x=1\)
\(x-1,2=1,1\)
\(x=1,1+1,2\)
\(x=2,3\)
