x = - \frac{17}{4} or x = \frac{19}{4}

Decimal Notation

x = - 4.25, x = 4.75

Solution steps

∣ 4 x - 1 ∣ = 18

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

4 x - 1 = - 18 or 4 x - 1 = 18

4 x - 1 = - 18 or 4 x - 1 = 18

x = - \frac{17}{4} or x = \frac{19}{4}

6 x^{2} = 1 - 7 x

- 3 \geq 2 - 5 x^{7}

a^{2} + 12 a + 20

4 x + 8 \geq - 12 or 3 x + 8 > 11

5 x^{2} - 70 x = - 230
