\frac{10 z + 4}{5} = 15

z = - \frac{79}{10} or z = \frac{71}{10}

Decimal Notation

z = - 7.9, z = 7.1

Solution steps

\frac{10 z + 4}{5} = 15

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{10 z + 4}{5} = - 15 or \frac{10 z + 4}{5} = 15

\frac{10 z + 4}{5} = - 15 or \frac{10 z + 4}{5} = 15

z = - \frac{79}{10} or z = \frac{71}{10}

- 41 a + 10 + 21 a^{2}

6 \cdot \frac{2}{3}

1 + 4

- 4 ∣ s + 10 ∣ < - 16

\frac{k}{10} \leq - 15
