(4x+1)/5 =(5x+8)/6

解答

\frac{4 x + 1}{5} = \frac{5 x + 8}{6}

解答

x = - 34

求解步骤

\frac{4 x + 1}{5} = \frac{5 x + 8}{6}

使用分式交叉相乘: 若

\frac{a}{b} = \frac{c}{d}

则

a \cdot d = b \cdot c

(4 x + 1) \cdot 6 = 5 (5 x + 8)

展开

(4 x + 1) \cdot 6 : 24 x + 6

展开

5 (5 x + 8) : 25 x + 40

24 x + 6 = 25 x + 40

将

6

到右边

24 x = 25 x + 34

将

25 x

para o lado esquerdo
