∣ 8 - 4 x ∣ = 3

x = \frac{5}{4} or x = \frac{11}{4}

Decimal Notation

x = 1.25, x = 2.75

Solution steps

∣ 8 - 4 x ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

8 - 4 x = - 3 or 8 - 4 x = 3

8 - 4 x = - 3 or 8 - 4 x = 3

x = \frac{5}{4} or x = \frac{11}{4}

(m - 1)^{3} - 2 m (m^{2} - 4) < 1

5 x^{2} = 2 x + 4

0.1 (0.5 m + 6) = 2

5 \cdot \frac{π}{180}

c^{2} = 3^{2} + 8^{2}
