∣ 8 x + 3 ∣ = 4

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

Decimal Notation

x = - 0.875, x = 0.125

Solution steps

∣ 8 x + 3 ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

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

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

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

8 (\frac{1}{2})

(\frac{3 a ^{2}}{b ^{3}})^{2} (\frac{- 2 a}{3 b})^{2}

\frac{1}{2} x^{2} - 2 = - 2 x^{2} - 3 x + 2

a^{- \frac{1}{2}}

- 2 + \frac{4}{3}
