2 ∣ 8 x + 1 ∣ + 1 = 6

x = - \frac{7}{16} or x = \frac{3}{16}

Decimal Notation

x = - 0.4375, x = 0.1875

Solution steps

2 ∣ 8 x + 1 ∣ + 1 = 6

Move

1

to the right side

2 ∣ 8 x + 1 ∣ = 5

Divide both sides by

2

∣ 8 x + 1 ∣ = \frac{5}{2}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

8 x + 1 = - \frac{5}{2} or 8 x + 1 = \frac{5}{2}

8 x + 1 = - \frac{5}{2} or 8 x + 1 = \frac{5}{2}

x = - \frac{7}{16} or x = \frac{3}{16}

3 ∣ y + 4 ∣ - 9 = 0

∣ 2 x ∣ = 6 - x

∣ 8 x + 2 ∣ = 10

- ∣ 4 + x ∣ = 10

∣ - 9 + 7 x ∣ = 3
