solvefor a, a/(b+c)+d/(b-c)= 2/(b+c)

解

解く

a, \frac{a}{b + c} + \frac{d}{b - c} = \frac{2}{b + c}

a = 2 - \frac{d ( b + c )}{b - c}; b + c \neq = 0

解答ステップ

\frac{a}{b + c} + \frac{d}{b - c} = \frac{2}{b + c}

\frac{d}{b - c}

を右側に移動します

\frac{a}{b + c} = \frac{2}{b + c} - \frac{d}{b - c}

以下で両辺を乗じる:

b + c

a = 2 - \frac{d ( b + c )}{b - c}; b + c \neq = 0
