7 ∣ 6 + 8 x ∣ + 4 = 74

x = - 2 or x = \frac{1}{2}

Decimal Notation

x = - 2, x = 0.5

Solution steps

7 ∣ 6 + 8 x ∣ + 4 = 74

Move

4

to the right side

7 ∣ 6 + 8 x ∣ = 70

Divide both sides by

7

∣ 6 + 8 x ∣ = 10

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

6 + 8 x = - 10 or 6 + 8 x = 10

6 + 8 x = - 10 or 6 + 8 x = 10

x = - 2 or x = \frac{1}{2}

∣ - x ∣ = 8

∣ 2 y + 5 ∣ = 10

∣ x - 6 ∣ + 7 = 8

4 = ∣ x - 3 ∣ - 13

\frac{x}{6} = 7
