x = - 5

Solution steps

∣ 2 x + 11 ∣ = ∣ 2 x + 9 ∣

Find positive and negative intervals

x < - \frac{11}{2}, - \frac{11}{2} \leq x < - \frac{9}{2}, x \geq - \frac{9}{2}

Solve the inequality for each interval

No Solution or x = - 5

x = - 5

(x)^{3}

(\frac{b}{2})^{2}

\frac{x}{5} - 1 = \frac{x}{8} + 5

\frac{9 ^{4}}{16} - \frac{5 ^{4}}{16}

400 \cdot (1 + 0.05)^{5}
