(((x-726000)0.64))/(6000000)=(((x-762000-350000)0.64))/(5000000)

解答

\frac{( ( x - 726000 ) \cdot 0.64 )}{6000000} = \frac{( ( x - 762000 - 350000 ) \cdot 0.64 )}{5000000}

解答

x = 3042000

求解步骤

\frac{( ( x - 726000 ) \cdot 0.64 )}{6000000} = \frac{( ( x - 762000 - 350000 ) \cdot 0.64 )}{5000000}

在两边乘以

1000000

\frac{8 ( x - 726000 )}{75} = \frac{16 ( x - 1112000 )}{125}

使用分式交叉相乘: 若

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

则

a \cdot d = b \cdot c

8 (x - 726000) \cdot 125 = 75 \cdot 16 (x - 1112000)

化简

1000 (x - 726000) = 1200 (x - 1112000)

展开

1000 (x - 726000) : 1000 x - 726000000

展开

1200 (x - 1112000) : 1200 x - 1334400000

1000 x - 726000000 = 1200 x - 1334400000

将

726000000

到右边

1000 x = 1200 x - 608400000

将

1200 x

para o lado esquerdo

- 200 x = - 608400000

两边除以

- 200

x = 3042000
