x = 2.4, x = 4

Solution steps

∣ 5 x - 16 ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5 x - 16 = - 4 or 5 x - 16 = 4

5 x - 16 = - 4 or 5 x - 16 = 4

x = \frac{12}{5} or x = 4

\frac{\frac{1}{5}}{- 3}

10 n^{2} + 8 n - 20610 = 0

\frac{3 + 2 i}{2 + i}

12 x^{2} + 17 x - 5

\frac{x}{5} + 1 = 5
