solvefor a, 1/a+1/b =c

解答

求解

a, \frac{1}{a} + \frac{1}{b} = c

解答

a = - \frac{b}{1 - b c}; b \neq = \frac{1}{c}

求解步骤

\frac{1}{a} + \frac{1}{b} = c

乘以最小公倍数

b + a = c ab

将

b

到右边

a = c ab - b

将

c ab

para o lado esquerdo

a - c ab = - b

分解

a - c ab : a (1 - b c)

a (1 - b c) = - b

两边除以

1 - b c; b \neq = \frac{1}{c}

a = - \frac{b}{1 - b c}; b \neq = \frac{1}{c}

(5x+1}{x+2}+\frac{x-1)/x =2

\frac{5 x + 1}{x + 2} + \frac{x - 1}{x} = 2

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

-3/(x^2+3x)+6= 1/(x+3)

- \frac{3}{x ^{2} + 3 x} + 6 = \frac{1}{x + 3}

x+3/(x+3)= 7/(x+3)

x + \frac{3}{x + 3} = \frac{7}{x + 3}

(2x)/(x-5)+1/(x-3)=3

\frac{2 x}{x - 5} + \frac{1}{x - 3} = 3
