solvefor x,6x+4y=20

解答

求解

x, 6 x + 4 y = 20

x = \frac{2 ( - y + 5 )}{3}

求解步骤

6 x + 4 y = 20

将

4 y

到右边

6 x = 20 - 4 y

两边除以

6

x = \frac{2 ( - y + 5 )}{3}

so l v e f or x, 2 y - 3 x = - 14

\frac{4 x + 3}{6} - 2 x + \frac{3 x + 1}{4} + 1 = 0

- 3 (x - 1) + 7 x = 27

3 x - 11 + 4 x + 2 = - x + 47

\frac{2 x - 1}{2} - \frac{x + 13}{24} = 3 x + \frac{5 ( x + 1 )}{8}
