∣ 5 a - 1 ∣ = 9

a = - \frac{8}{5} or a = 2

Solution steps

∣ 5 a - 1 ∣ = 9

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5 a - 1 = - 9 or 5 a - 1 = 9

5 a - 1 = - 9 or 5 a - 1 = 9

a = - \frac{8}{5} or a = 2

(4^{- 4})^{2}

\frac{1 + \frac{2}{c - 1}}{1 - \frac{2}{c - 1}}

x^{2} - 35 x + 300 = 0

- \frac{5}{8} + \frac{1}{2}

4 ∣ x - 1 ∣ + 2 > 6
