12 = 5 ∣ x + 1 ∣ + 3

x = - \frac{14}{5} or x = \frac{4}{5}

Decimal Notation

x = - 2.8, x = 0.8

Solution steps

12 = 5 ∣ x + 1 ∣ + 3

Switch sides

5 ∣ x + 1 ∣ + 3 = 12

Move

3

to the right side

5 ∣ x + 1 ∣ = 9

Divide both sides by

5

∣ x + 1 ∣ = \frac{9}{5}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x + 1 = - \frac{9}{5} or x + 1 = \frac{9}{5}

x + 1 = - \frac{9}{5} or x + 1 = \frac{9}{5}

x = - \frac{14}{5} or x = \frac{4}{5}

∣ 8 + 10 n ∣ = 52

x^{3} - 4 = 7 - x

∣ - 2 x + 5 ∣ = 13

f (x) = ∣ n ∣ + 1, f (4)

∣ x - 2 ∣ = 3 x + 4
