5/3 x+1/3 x= 131/3+8/3 x

解答

\frac{5}{3} x + \frac{1}{3} x = \frac{131}{3} + \frac{8}{3} x

x = - \frac{131}{2}

十进制

x = - 65.5

求解步骤

\frac{5}{3} x + \frac{1}{3} x = \frac{131}{3} + \frac{8}{3} x

将

\frac{8}{3} x

para o lado esquerdo

- \frac{2}{3} x = \frac{131}{3}

在两边乘以

3

- 2 x = 131

两边除以

- 2

x = - \frac{131}{2}

\frac{1}{4} x + \frac{5}{3} x - 4 = 2 - \frac{1}{12} x

so l v e f or x, 3 y - 2 x - 4 = 0

so l v e f or f, f (2) = \frac{3 x}{x ^{2} + 1}

2 - 6 x = 22 + 4 x

so l v e f or x, 8 x - y = - 5
