0.2x+6=-7.3|x-9|+22,y=0

解答

0.2 x + 6 = - 7.3 ∣ x - 9 ∣ + 22, y = 0

解答

(x = 7, y = 0 x = \frac{817}{75}, y = 0)

求解步骤

[0.2 x + 6 = - 7.3 ∣ x - 9 ∣ + 22 y = 0]

[0.2 x + 6 = - 7.3 ∣ x - 9 ∣ + 22]

0.2 x + 6 = - 7.3 ∣ x - 9 ∣ + 22 : x = 7 or x = \frac{817}{75}

对于

x = 7 : y = 0

对于

x = \frac{817}{75} : y = 0

方程组的解为:

(x = 7, y = 0 x = \frac{817}{75}, y = 0)

∣ 3 x - 2 ∣ + 6 = 10

x^{2} - 5 ∣ x ∣ = 0

2 ∣ x - 1 ∣ + 4 = 5

∣ 9 + 4 x ∣ = 15

a|x+3|+(5-a)|x-3|-6=0

a ∣ x + 3 ∣ + (5 - a) ∣ x - 3 ∣ - 6 = 0
