∣ 0.6 - 0.4 y ∣ = 2

y = - \frac{7}{2} or y = \frac{13}{2}

Decimal Notation

y = - 3.5, y = 6.5

Solution steps

∣ 0.6 - 0.4 y ∣ = 2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

0.6 - 0.4 y = - 2 or 0.6 - 0.4 y = 2

0.6 - 0.4 y = - 2 or 0.6 - 0.4 y = 2

y = - \frac{7}{2} or y = \frac{13}{2}

∣ 9 x + 4 ∣ = 8

∣ 2 x - 1 ∣ - 2 = 15

∣ 4 x + 3 ∣ - 9 = - 5

∣ 8 + 5 x ∣ = - x + 7

- 7 ∣ 10 x - 3 ∣ - 4 = - 25
