∣ - 4 x ∣ = 11

x = - \frac{11}{4} or x = \frac{11}{4}

Solution steps

∣ - 4 x ∣ = 11

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 4 x = - 11 or - 4 x = 11

- 4 x = - 11 or - 4 x = 11

x = - \frac{11}{4} or x = \frac{11}{4}

100 f - 50 = 50 f + 50

x^{2} - 13 x + 36 \leq 0

x^{4} - 45 x^{2} + 324

3 (x + 5) = 60
