solvefor x,3y=6x-9

解答

求解

x, 3 y = 6 x - 9

x = \frac{y + 3}{2}

求解步骤

3 y = 6 x - 9

交换两边

6 x - 9 = 3 y

将

9

到右边

6 x = 3 y + 9

两边除以

6

x = \frac{y + 3}{2}

\frac{3}{2} a - \frac{4}{3} a = - \frac{10}{3} + 2 \frac{2}{3} a

so l v e f or x, 4 x + 6 y - 8 = 0

14 + 8 (u + 12) = 2 (6 u + 19)

5 x - 5 + 2 x + 10 = 180

so l v e f or x, \frac{2 x}{3} + \frac{y}{5} = 6
