solvefor E,T=(4U)/E

解答

求解

E, T = \frac{4 U}{E}

E = \frac{4 U}{T}; T \neq = 0

求解步骤

T = \frac{4 U}{E}

在两边乘以

E

TE = 4 U

两边除以

T; T \neq = 0

E = \frac{4 U}{T}; T \neq = 0

\frac{1}{x + 1} = \frac{5 x - 6}{6 x}

\frac{5.8}{x - 62} = - 4

so l v e f or x, \frac{1}{x} = t

\frac{- 4}{2 x} + \frac{5}{x} = - 9

\frac{8}{p} = 2 p - 6
