((x(a+b)))/((a+b))+1/(((a+b)^2))=1

解答

\frac{( x ( a + b ) )}{( a + b )} + \frac{1}{( ( a + b ) ^{2} )} = 1

x = 1 - \frac{1}{( a + b ) ^{2}}

求解步骤

\frac{( x ( a + b ) )}{( a + b )} + \frac{1}{( ( a + b ) ^{2} )} = 1

消掉

\frac{x ( a + b )}{a + b} : x

x + \frac{1}{( a + b ) ^{2}} = 1

将

\frac{1}{( a + b ) ^{2}}

到右边

x = 1 - \frac{1}{( a + b ) ^{2}}

so l v e f or x, \frac{x}{3} - \frac{y}{5} = \frac{22}{15}

so l v e f or y, (d^{2} + a^{2}) y = 0

so l v e f or x, 2 (x - 3) + 5 y = 18

4 (x^{1}) + 4 x = 2 (3 x - 1)

so l v e f or x, 30 = (2 x + 1) + 2 y
