-d/5-1=-6

解答

- \frac{d}{5} - 1 = - 6

d = 25

求解步骤

- \frac{d}{5} - 1 = - 6

将

1

到右边

- \frac{d}{5} = - 5

在两边乘以

5

- d = - 25

两边除以

- 1

d = 25

so l v e f or x, - 4 x + 3 y = - 2

\frac{3}{4} m - 2 (m - 1) = \frac{1}{4} m + 5

132 x + 25 - 33 x = - 10 - x + 85

\frac{2}{7} k - \frac{3}{8} = - \frac{19}{8}

\frac{x}{2} + \frac{x}{6} = 4
