-2|2.2x-3.3|=-6.6

- 2 ∣ 2.2 x - 3.3 ∣ = - 6.6

x = 0 or x = 3

Solution steps

- 2 ∣ 2.2 x - 3.3 ∣ = - 6.6

Divide both sides by

- 2

∣ 2.2 x - 3.3 ∣ = 3.3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2.2 x - 3.3 = - 3.3 or 2.2 x - 3.3 = 3.3

2.2 x - 3.3 = - 3.3 or 2.2 x - 3.3 = 3.3

x = 0 or x = 3

∣ 4 - x ∣ - ∣ 7 - x ∣ = 11

∣ x ∣ = \frac{8 ( \frac{1}{2} ) ^{3} + 1}{4}

x^{2} - 3 ∣ x ∣ - 4 = 0

x^{2} - x = x^{2} - x

∣ x ∣ - ∣ x - 2 ∣ = 2
