∣ 4 x - 1 ∣ = 20

x = - \frac{19}{4} or x = \frac{21}{4}

Solution steps

∣ 4 x - 1 ∣ = 20

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

4 x - 1 = - 20 or 4 x - 1 = 20

4 x - 1 = - 20 or 4 x - 1 = 20

x = - \frac{19}{4} or x = \frac{21}{4}

15 x^{2} - 23 x + 4

(\frac{- 5}{2})^{2}

21 a^{2} + 11 a - 2

(\frac{8}{3})^{- 1}

(64)^{\frac{1}{3}}
