5/6 x-7/4+2/3 x=2x-5/12+x/3

解答

\frac{5}{6} x - \frac{7}{4} + \frac{2}{3} x = 2 x - \frac{5}{12} + \frac{x}{3}

解答

x = - \frac{8}{5}

+1

十进制

x = - 1.6

求解步骤

\frac{5}{6} x - \frac{7}{4} + \frac{2}{3} x = 2 x - \frac{5}{12} + \frac{x}{3}

将

\frac{7}{4}

到右边

\frac{5}{6} x + \frac{2}{3} x = \frac{4 + 7 x}{3}

乘以最小公倍数

9 x = 2 (7 x + 4)

展开

2 (7 x + 4) : 14 x + 8

9 x = 14 x + 8

将

14 x

para o lado esquerdo

- 5 x = 8

两边除以

- 5

x = - \frac{8}{5}

流行的例子

3(x+5)+6x=-3(1-3x)+18

3 (x + 5) + 6 x = - 3 (1 - 3 x) + 18

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

\frac{x}{2} + \frac{2}{3} = \frac{x}{3} + 1 - \frac{1}{2} (1 - x + \frac{1}{3})

7 x - 2 x - 3 = 3 x + x - 5

2 (3 x + 8) = 2 x

- 2 x + 1 = 5
