∣ 5 x + 9 ∣ = 4 x^{4} x

x = 1.31218 \dots

Solution steps

∣ 5 x + 9 ∣ = 4 x^{4} x

Find positive and negative intervals

x < - \frac{9}{5}, x \geq - \frac{9}{5}

Solve the inequality for each interval

No Solution or x = 1.31218 \dots

x = 1.31218 \dots

\frac{x}{10} = 2

2 ∣ x - 3 ∣ = 10

∣ 6 x - 7 ∣ + 3 = 12

- 2 ∣ x + 5 ∣ + 3 x = - 22

∣ 6 x - 12 ∣ = 18
