(n-1)/(2n)=0.49

\frac{n - 1}{2 n} = 0.49

n = 50

Solution steps

\frac{n - 1}{2 n} = 0.49

Multiply both sides by

n

\frac{n - 1}{2} = 0.49 n

Multiply both sides by

100

50 (n - 1) = 49 n

Expand

50 (n - 1) : 50 n - 50

50 n - 50 = 49 n

Move

50

to the right side

50 n = 49 n + 50

Move

49 n

to the left side

n = 50

Verify Solutions

Find undefined (singularity) points:

n = 0

Combine undefined points with solutions:

n = 50

0.345 = \frac{16}{x}

x^{- 2} + 9 x^{- 1} + 8 = 0

x^{- 1} + 1 = x

1.4 = \frac{2.65}{x - 1}

\frac{- 2}{3} + \frac{8}{3 x} = 2
