-7x+5ax+119+115/19 ax=-18x+5a+312/51 a

解答

- 7 x + 5 a x + 119 + \frac{115}{19} a x = - 18 x + 5 a + \frac{312}{51} a

解答

x = \frac{3591 a - 38437}{17 ( 210 a + 209 )}; a \neq = - \frac{209}{210}

求解步骤

- 7 x + 5 a x + 119 + \frac{115}{19} a x = - 18 x + 5 a + \frac{312}{51} a

\frac{312}{51} a = \frac{104 a}{17}

- 7 x + 5 a x + 119 + \frac{115}{19} a x = - 18 x + 5 a + \frac{104 a}{17}

将

119

到右边

- 7 x + 5 a x + \frac{115}{19} a x = - 18 x + 5 a + \frac{104 a}{17} - 119

将

18 x

para o lado esquerdo

\frac{210}{19} a x + 11 x = 5 a + \frac{104 a}{17} - 119

在两边乘以

19

210 a x + 209 x = 95 a + \frac{1976 a}{17} - 2261

分解

210 a x + 209 x : x (210 a + 209)

x (210 a + 209) = 95 a + \frac{1976 a}{17} - 2261

两边除以

210 a + 209; a \neq = - \frac{209}{210}

x = \frac{3591 a - 38437}{17 ( 210 a + 209 )}; a \neq = - \frac{209}{210}

流行的例子

19 = \frac{h}{3} - 8

3 c + 6 = 12

7/3 y-6=-1/2 y-3/4

\frac{7}{3} y - 6 = - \frac{1}{2} y - \frac{3}{4}

y = \frac{1}{2} (2)^{2}

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