4 - 7 ∣ 5 x - 1 ∣ = - 45

x = - \frac{6}{5} or x = \frac{8}{5}

Solution steps

4 - 7 ∣ 5 x - 1 ∣ = - 45

Move

4

to the right side

- 7 ∣ 5 x - 1 ∣ = - 49

Divide both sides by

- 7

∣ 5 x - 1 ∣ = 7

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5 x - 1 = - 7 or 5 x - 1 = 7

5 x - 1 = - 7 or 5 x - 1 = 7

x = - \frac{6}{5} or x = \frac{8}{5}

∣ 3 x - 6 ∣ + x^{2} - 2 x = 30

- ∣ b ∣ = - 1

15 = ∣ p ∣ + 3

∣ - 8 w ∣ = 0

\frac{1}{2} x - 4 = 3
