∣ - 4 n - 3 ∣ = 9

n = - 3 or n = \frac{3}{2}

Solution steps

∣ - 4 n - 3 ∣ = 9

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 4 n - 3 = - 9 or - 4 n - 3 = 9

- 4 n - 3 = - 9 or - 4 n - 3 = 9

n = - 3 or n = \frac{3}{2}

\frac{x}{5} = 4

∣ 9 - 12 x ∣ = 45

x^{2} + 2 x - 10 = ∣ x + 2 ∣ + 6

∣ r - 80 ∣ = 1

∣ z ∣ = a
