\bar{AB}=((3-1)/(4-2))(x-2)

解答

\overset{ˉ}{A B} = (\frac{3 - 1}{4 - 2}) (x - 2)

解答

x = \overset{ˉ}{A B} + 2

求解步骤

\overset{ˉ}{A B} = (\frac{3 - 1}{4 - 2}) (x - 2)

交换两边

(\frac{3 - 1}{4 - 2}) (x - 2) = \overset{ˉ}{A B}

去除括号:

(a) = a

\frac{3 - 1}{4 - 2} (x - 2) = \overset{ˉ}{A B}

分式相乘:

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

\frac{( 3 - 1 ) ( x - 2 )}{4 - 2} = \overset{ˉ}{A B}

整理后得

\frac{2 ( x - 2 )}{2} = \overset{ˉ}{A B}

数字相除:

\frac{2}{2} = 1

x - 2 = \overset{ˉ}{A B}

将

2

到右边

x = \overset{ˉ}{A B} + 2
