x/8+x/6 =-7/3

解答

\frac{x}{8} + \frac{x}{6} = - \frac{7}{3}

x = - 8

求解步骤

\frac{x}{8} + \frac{x}{6} = - \frac{7}{3}

乘以最小公倍数

7 x = - 56

两边除以

7

x = - 8

so l v e f or y, 3 x - 2 y = 3

so l v e f or y, 4 x + 8 y = 20

\frac{x}{12} + \frac{x}{8} + x = - \frac{29}{6}

so l v e f or y, 2 x - 3 y = 15

8 - 5 (8 + 3 x) = 13
