|4x|-12=4

∣ 4 x ∣ - 12 = 4

x = - 4 or x = 4

Solution steps

∣ 4 x ∣ - 12 = 4

Move

12

to the right side

∣ 4 x ∣ = 16

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

4 x = - 16 or 4 x = 16

4 x = - 16 or 4 x = 16

x = - 4 or x = 4

2 + 6 (x - 4) = 3 x - 18 + 3 x

\frac{3 - i}{3 + i}

5 x - 4 \cdot (- 1 + 6 x) = 8 - (3 x - 5) - 2

x = 2 - x

- x^{2} + 2 x + 24 = 0
