-2h= 4/3 (6-3h)+h-3/4 (4h+8)

解答

- 2 h = \frac{4}{3} (6 - 3 h) + h - \frac{3}{4} (4 h + 8)

解答

h = \frac{1}{2}

+1

十进制

h = 0.5

求解步骤

- 2 h = \frac{4}{3} (6 - 3 h) + h - \frac{3}{4} (4 h + 8)

乘

\frac{4}{3} (6 - 3 h) : \frac{4 ( - 3 h + 6 )}{3}

- 2 h = \frac{4 ( - 3 h + 6 )}{3} + h - \frac{3}{4} (4 h + 8)

乘

\frac{3}{4} (4 h + 8) : \frac{3 ( 4 h + 8 )}{4}

- 2 h = \frac{4 ( 6 - 3 h )}{3} + h - \frac{3 ( 4 h + 8 )}{4}

乘以最小公倍数

- 24 h = 48 (- h + 2) + 12 h - 36 (h + 2)

展开

48 (- h + 2) + 12 h - 36 (h + 2) : - 72 h + 24

- 24 h = - 72 h + 24

将

72 h
