(m(x+n)-n(x-m))/(m(m+n)+n(n-m))=1

解答

\frac{m ( x + n ) - n ( x - m )}{m ( m + n ) + n ( n - m )} = 1

解答

x = m - n; m (m + n) + n (n - m) \neq = 0, m \neq = n

求解步骤

\frac{m ( x + n ) - n ( x - m )}{m ( m + n ) + n ( n - m )} = 1

在两边乘以

m (m + n) + n (n - m)

m x - n x + 2 mn = m^{2} + n^{2}; m (m + n) + n (n - m) \neq = 0

将

2 mn

到右边

m x - n x = m^{2} + n^{2} - 2 mn; m (m + n) + n (n - m) \neq = 0

分解

m x - n x : x (m - n)

x (m - n) = m^{2} + n^{2} - 2 mn; m (m + n) + n (n - m) \neq = 0

两边除以

m - n; m (m + n) + n (n - m) \neq = 0, m \neq = n

x = m - n; m (m + n) + n (n - m) \neq = 0, m \neq = n

solvefor b,(a-b)/(c+d)=f

so l v e f or b, \frac{a - b}{c + d} = f

5 (p - 3) = 63

0 = - 2 x

- 13 = m - 7

8=-18+3/8 (16-40n)

8 = - 18 + \frac{3}{8} (16 - 40 n)
