solvefor x,6x-y/3 = 5/6

解答

求解

x, 6 x - \frac{y}{3} = \frac{5}{6}

x = \frac{5 + 2 y}{36}

求解步骤

6 x - \frac{y}{3} = \frac{5}{6}

将

\frac{y}{3}

到右边

6 x = \frac{5}{6} + \frac{y}{3}

两边除以

6

x = \frac{5 + 2 y}{36}

2 \frac{x}{3} + \frac{42}{5} = \frac{311}{30}

(0.5) x = - 7

so l v e f or x, - 3 x + 21 y = - 27

7 - 14 y + 26 y = - 5

13.5 x + 10.5 \cdot (50 - x) = 50 \cdot 11.3
