k/3-11=-5

解答

\frac{k}{3} - 11 = - 5

k = 18

求解步骤

\frac{k}{3} - 11 = - 5

将

11

到右边

\frac{k}{3} = 6

在两边乘以

3

k = 18

8 (x + \frac{1}{2}) = 5 (x + 1) + \frac{1}{4}

(20 (\frac{12}{100})) + x (\frac{20}{100}) = (20 + x) (\frac{16}{100})

5 x + 46 = 2 (x + 5) + 9

so l v e f or x, y - 4 = \frac{1}{2} (x - 8)

7 - x = 7
