-6-1.5(4b+8)=3(-6-2b)

解答

- 6 - 1.5 (4 b + 8) = 3 (- 6 - 2 b)

解答

对所有 b 为真

求解步骤

- 6 - 1.5 (4 b + 8) = 3 (- 6 - 2 b)

To eliminate decimal points, multiply by 10 for every digit after the decimal pointThere is one digit to the right of the decimal point, therefore multiply by

10

- 6 \cdot 10 - 1.5 (4 b + 8) \cdot 10 = 3 (- 6 - 2 b) \cdot 10

整理后得

- 60 - 15 (4 b + 8) = 30 (- 6 - 2 b)

展开

- 60 - 15 (4 b + 8) : - 60 b - 180

展开

30 (- 6 - 2 b) : - 180 - 60 b

- 60 b - 180 = - 180 - 60 b

将

180

到右边

- 60 b = - 60 b

将

60 b

para o lado esquerdo

0 = 0

流行的例子

2 x + 60 + x = 180

y = f (- 1)

\frac{k}{6} = 8

3/2+(2x+1)/6 =-1

\frac{3}{2} + \frac{2 x + 1}{6} = - 1

m + 9 = - 2
