solvefor T,f= 1/T

解答

求解

T, f = \frac{1}{T}

T = \frac{1}{f}; f \neq = 0

求解步骤

f = \frac{1}{T}

在两边乘以

T

f T = 1

两边除以

f; f \neq = 0

T = \frac{1}{f}; f \neq = 0

\frac{4}{x} = \frac{2}{19}

- \frac{2}{7} = \frac{12}{x}

- \frac{2}{9} = \frac{8}{- 3 x}

\frac{200 P - 5000}{200 P} = 0.3

\frac{2 x - 1}{x + 2} = \frac{8}{7}
