solvefor t,r= d/t

解答

求解

t, r = \frac{d}{t}

t = \frac{d}{r}; r \neq = 0

求解步骤

r = \frac{d}{t}

在两边乘以

t

r t = d

两边除以

r; r \neq = 0

t = \frac{d}{r}; r \neq = 0

so l v e f or y, x = \frac{2 y - 3}{y + 1}

3 x^{- 2} = 27

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

\frac{z - 1}{z + 1} = \frac{2}{z + 4}

\frac{33 - x}{5 x} = 2
