Question

1 - 1 phan x - 1 phan 3 = 1 phan 6

ai lam nhanh tui tick

 

Answer 1

đề ntn phải ko

1-\(\frac{1}{x}-\frac{1}{3}=\frac{1}{6}\)

\(=>1-\frac{1}{x}=\frac{1}{6}+\frac{1}{3}\)

\(=>1-\frac{1}{x}=\frac{1}{2}\)

\(=>-\frac{1}{x}=1-\frac{1}{2}\)

\(-\frac{1}{x}=\frac{1}{2}\) 

\(=>x=-2\)

Answer 2

1-1/x-1/3=1/6

1-1/x=1/6+1/3

1-1/x=3/6

1/x=1-3/6

1/x=3/6

1/x=1/2

<=>x=2
