-2-5/6 b-3/2 b= 1/2 b+4-1/3 b

解答

- 2 - \frac{5}{6} b - \frac{3}{2} b = \frac{1}{2} b + 4 - \frac{1}{3} b

解答

b = - \frac{12}{5}

+1

十进制

b = - 2.4

求解步骤

- 2 - \frac{5}{6} b - \frac{3}{2} b = \frac{1}{2} b + 4 - \frac{1}{3} b

将

2

到右边

- \frac{5}{6} b - \frac{3}{2} b = \frac{1}{6} b + 6

将

\frac{1}{6} b

para o lado esquerdo

- \frac{5}{2} b = 6

在两边乘以

2

- 5 b = 12

两边除以

- 5

b = - \frac{12}{5}

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

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

5 x + 10 = 6 x

2/5 (5+10s)=-3/2 (2/3 s-4)+3

\frac{2}{5} (5 + 10 s) = - \frac{3}{2} (\frac{2}{3} s - 4) + 3

21 = \frac{2}{11} a + 11

x^2+4x+1+3(x+1)=(x-1)(x+4)

x^{2} + 4 x + 1 + 3 (x + 1) = (x - 1) (x + 4)
