15x+10=7x-14

解答

15 x + 10 = 7 x - 14

x = - 3

求解步骤

15 x + 10 = 7 x - 14

将

10

到右边

15 x = 7 x - 24

将

7 x

para o lado esquerdo

8 x = - 24

两边除以

8

x = - 3

- 8 + 4 g - 2 h + k = 24.4 g - 2 h + k

so l v e f or g, g (s) = \frac{k}{s} (s + 1)

so l v e f or x, g^{92} x + 4 = 26.32 x + 3 + 3

14.13 = x - 4.25

2 x - 3 x - (9 x + 1) - 8 = 12 x - 9 - [3 x - (5 - 2 x) - 10] + 18 x
