∣ - 7 d ∣ = 8

d = - \frac{8}{7} or d = \frac{8}{7}

Decimal Notation

d = - 1.14285 \dots, d = 1.14285 \dots

Solution steps

∣ - 7 d ∣ = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 7 d = - 8 or - 7 d = 8

- 7 d = - 8 or - 7 d = 8

d = - \frac{8}{7} or d = \frac{8}{7}

∣ - 3 + 4 r ∣ = 29

e^{x} - x^{2} = 0

∣ 2 y ∣ = 0

8 ∣ 8 - 5 x ∣ = 8 x + 8

8 = 2 ∣ m - 2 ∣
