x-b-c/a+x-c-a/b+x-a-b/c =3

解答

x - b - \frac{c}{a} + x - c - \frac{a}{b} + x - a - \frac{b}{c} = 3

解答

x = \frac{3 b c a + b ^{2} c a + b c ^{2} a + b c a ^{2} + b c ^{2} + c a ^{2} + b ^{2} a}{3 b c a}

求解步骤

x - b - \frac{c}{a} + x - c - \frac{a}{b} + x - a - \frac{b}{c} = 3

对同类项分组

x + x + x - b - c - a - \frac{c}{a} - \frac{a}{b} - \frac{b}{c} = 3

同类项相加:

x + x + x = 3 x

3 x - b - c - a - \frac{c}{a} - \frac{a}{b} - \frac{b}{c} = 3

将

b

到右边

3 x - c - a - \frac{c}{a} - \frac{a}{b} - \frac{b}{c} = 3 + b

将

c

到右边

3 x - a - \frac{c}{a} - \frac{a}{b} - \frac{b}{c} = 3 + b + c

将

a

到右边

3 x - \frac{c}{a} - \frac{a}{b} - \frac{b}{c} = 3 + b + c + a

将

\frac{c}{a}

到右边

3 x - \frac{a}{b} - \frac{b}{c} = 3 + b + c + a + \frac{c}{a}

将

\frac{a}{b}

到右边

3 x - \frac{b}{c} = 3 + b + c + a + \frac{c}{a} + \frac{a}{b}

将

\frac{b}{c}

到右边

3 x = 3 + b + c + a + \frac{c}{a} + \frac{a}{b} + \frac{b}{c}

两边除以

3

x = \frac{3 b c a + b ^{2} c a + b c ^{2} a + b c a ^{2} + b c ^{2} + c a ^{2} + b ^{2} a}{3 b c a}

\frac{d}{9} = 8

\frac{h}{0.5} = 7

20 y + 2 y = 11

- 6 x - 3 = 4 + 3 x

solvefor x,x(z)= 1/(((z-1/4)(z-1/z)))

so l v e f or x, x (z) = \frac{1}{( ( z - \frac{1}{4} ) ( z - \frac{1}{z} ) )}
