solvefor b,a= 1/2 h(a/b)

解答

求解

b, a = \frac{1}{2} h (\frac{a}{b})

b = \frac{h}{2}; a \neq = 0

求解步骤

a = \frac{1}{2} h (\frac{a}{b})

化简

\frac{1}{2} h (\frac{a}{b}) : \frac{ah}{2 b}

a = \frac{ah}{2 b}

在两边乘以

b

ab = \frac{ah}{2}

两边除以

a; a \neq = 0

b = \frac{h}{2}; a \neq = 0

y^{^{''}} (t) + y^{^{'}} (t) - 2 y = \frac{0}{y} (0) = 4, y^{^{'}} (0) = - 5

a = x + \frac{1}{x} e n, 1 < x < 5

\frac{3 x + 5}{3 - 2 x} = \frac{5}{3}

\frac{( x ^{2} + 8 x + 16 )}{( x + 4 )} = \frac{- 1}{( x + 2 )}

\frac{x + 1}{x} = \frac{c + 1}{c}
