(5x)/6-(3-x)/8 =(4x+3)/(12)

解答

\frac{5 x}{6} - \frac{3 - x}{8} = \frac{4 x + 3}{12}

x = 1

求解步骤

\frac{5 x}{6} - \frac{3 - x}{8} = \frac{4 x + 3}{12}

乘以最小公倍数

20 x - 3 (- x + 3) = 2 (4 x + 3)

乘开

- 3 (- x + 3) : 3 x - 9

20 x + 3 x - 9 = 2 (4 x + 3)

10 x^{2} - 21 x = - 2

18 - 4 v = 42

s im pl i f y \frac{3 - 4 i}{8 + 2 i}

f a c t or 64 a^{3} + 125 b^{3}

\frac{2 ( X - 1 )}{6} + \frac{3 ( X - 2 )}{6} = 2
