solvefor x,u=(x+y)/(kx)

解答

求解

x, u = \frac{x + y}{k x}

解答

x = \frac{y}{k u - 1}; k \neq = 0, u \neq = \frac{1}{k}

求解步骤

u = \frac{x + y}{k x}

在两边乘以

x

ux = \frac{x + y}{k}

在两边乘以

k

ux k = x + y; k \neq = 0

将

x

para o lado esquerdo

ux k - x = y; k \neq = 0

分解

ux k - x : x (k u - 1)

x (k u - 1) = y; k \neq = 0

两边除以

k u - 1; k \neq = 0, u \neq = \frac{1}{k}

x = \frac{y}{k u - 1}; k \neq = 0, u \neq = \frac{1}{k}

(2x^2-8)/(x^2)=0

\frac{2 x ^{2} - 8}{x ^{2}} = 0

\frac{8}{x} = 1

2-3/(x+2)= 4/(x-2)

2 - \frac{3}{x + 2} = \frac{4}{x - 2}

(12)/x+(30)/x =1

\frac{12}{x} + \frac{30}{x} = 1

(x^2-1)/(x^2-4)=0

\frac{x ^{2} - 1}{x ^{2} - 4} = 0
