26= n/(2{26+(n-1)*0.5\)}

解答

26 = \frac{n}{2 \cdot { 2 \cdot 6 + ( n - 1 ) \cdot 0.5 }}

解答

n = - \frac{598}{25}

+1

十进制

n = - 23.92

求解步骤

26 = \frac{n}{2 { 2 \cdot 6 + ( n - 1 ) \cdot 0.5 }}

化简

\frac{n}{2 ( 2 \cdot 6 + ( n - 1 ) \cdot 0.5 )} : \frac{n}{2 ( 0.5 n + 11.5 )}

26 = \frac{n}{2 ( 0.5 n + 11.5 )}

在两边乘以

2 (0.5 n + 11.5)

52 (0.5 n + 11.5) = n

展开

52 (0.5 n + 11.5) : 26 n + 598

26 n + 598 = n

将

598

到右边

26 n = n - 598

将

n

para o lado esquerdo

25 n = - 598

两边除以

25

n = - \frac{598}{25}

验证解

找到无定义的点（奇点）:

n = - 23

将不在定义域的点与解相综合:

n = - \frac{598}{25}

(1/(8-x))^2+42=((x+1/8)^2-x)/(2+x(x-1))

(\frac{1}{8 - x})^{2} + 42 = \frac{( x + \frac{1}{8} ) ^{2} - x}{2 + x ( x - 1 )}

(a+4)/a =(4a)/(a^2+a-2)

\frac{a + 4}{a} = \frac{4 a}{a ^{2} + a - 2}

(q)=(5q^2)/(q+3+500)

(q) = \frac{5 q ^{2}}{q + 3 + 500}

3/(4-|x-3/2 |)= 1/6

\frac{3}{4 - x - \frac{3}{2}} = \frac{1}{6}

1/100 =(x/((1-x)))^2

\frac{1}{100} = (\frac{x}{( 1 - x )})^{2}
