7 ∣ 3 - 8 x ∣ = 28

x = - \frac{1}{8} or x = \frac{7}{8}

Solution steps

7 ∣ 3 - 8 x ∣ = 28

Divide both sides by

7

∣ 3 - 8 x ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

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

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

x = - \frac{1}{8} or x = \frac{7}{8}

2 \cdot (\frac{1}{2})^{- 1}

5 a^{2} + 3 a

(x - 1) (x - 2) < 0

(x + 3) (x + 2) (x - 4) < 0

x^{2} - 3 x - 70
