∣ 1 - 4 x ∣ + 8 = 13

x = - 1 or x = \frac{3}{2}

Decimal Notation

x = - 1, x = 1.5

Solution steps

∣ 1 - 4 x ∣ + 8 = 13

Move

8

to the right side

∣ 1 - 4 x ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

1 - 4 x = - 5 or 1 - 4 x = 5

1 - 4 x = - 5 or 1 - 4 x = 5

x = - 1 or x = \frac{3}{2}

36 - 3 x + 4 - x^{2} = 47 - 2 x^{2} + 9 x

\frac{x + 4}{- 2} \leq \frac{3 x - 8}{3}

2 x^{2} - 19 x - 33 = 0

(2 x + 3) (2 x - 3) + 5 x = 2 (x + 1) - 1

x^{4} - x^{3} - 13 x^{2} + x + 12
