solvefor a,ab-3=-2b

解答

求解

a, ab - 3 = - 2 b

a = \frac{- 2 b + 3}{b}; b \neq = 0

求解步骤

ab - 3 = - 2 b

将

3

到右边

ab = - 2 b + 3

两边除以

b; b \neq = 0

a = \frac{- 2 b + 3}{b}; b \neq = 0

2 x + 10 = 2.5 (x + 3)

lo g_{10} (6) (x) + lo g_{10} (6) (x - 9) = 2

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

36 x - 27 = 16 x + 10 x + 23

- 4 + w = - 10
