-(2x)/3-3/4 =(4x)/5-(5-x)/6

解答

- \frac{2 x}{3} - \frac{3}{4} = \frac{4 x}{5} - \frac{5 - x}{6}

x = \frac{5}{98}

十进制

x = 0.05102 \dots

求解步骤

- \frac{2 x}{3} - \frac{3}{4} = \frac{4 x}{5} - \frac{5 - x}{6}

乘以最小公倍数

- 40 x - 45 = 48 x - 10 (- x + 5)

乘开

- 10 (- x + 5) : 10 x - 50

- 40 x - 45 = 48 x + 10 x - 50

\frac{4}{5} x + \frac{9}{10} = 5 \frac{1}{5}

\frac{1}{2} x = 10

so l v e f or x, \frac{1}{5} x + 4 y = \frac{32}{8}

\frac{3}{2} + \frac{3}{4} a = \frac{1}{4} a - \frac{1}{2}

- \frac{1}{5} - \frac{5}{3} m = \frac{3}{5}
