3 ∣ 3 x ∣ + 4 = 16

x = - \frac{4}{3} or x = \frac{4}{3}

Decimal Notation

x = - 1.33333 \dots, x = 1.33333 \dots

Solution steps

3 ∣ 3 x ∣ + 4 = 16

Move

4

to the right side

3 ∣ 3 x ∣ = 12

Divide both sides by

3

∣ 3 x ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 x = - 4 or 3 x = 4

3 x = - 4 or 3 x = 4

x = - \frac{4}{3} or x = \frac{4}{3}

\frac{49 x ^{2} - 81}{x ^{2} - 64} \leq 0

- 7 (m - 81) = - 91

- 1 < - (- 9 x - 1) - \frac{5}{2} x

6 a x - 15 x

\frac{2 y}{3} - \frac{3}{4} = \frac{1}{12}
