140000+15060000(e)^{-0.02}=110*+20000

解答

140000 + 15060000 (e)^{- 0.02} = 110 \cdot + 20000

假

求解步骤

140000 + 15060000 (e)^{- 0.02} = 110 + 20000

化简

140000 + 15060000 e^{- 0.02} : 140000 + \frac{15060000}{e ^{0.02}}

化简

110 + 20000 : 20110

140000 + \frac{15060000}{e ^{0.02}} = 20110

两侧不相等

假

15 - x + 4 x = - 6

so l v e f or x, 3 x + 6 y - 3 = 0

so l v e f or x, (x - 5) 2 = - 8 (y - 6)

so l v e f or x, 9 x - 3 y - 36 = 0

3 a + 6 = a + 18
