∣ 2 x + 1 ∣ = 10

x = - \frac{11}{2} or x = \frac{9}{2}

Solution steps

∣ 2 x + 1 ∣ = 10

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x + 1 = - 10 or 2 x + 1 = 10

2 x + 1 = - 10 or 2 x + 1 = 10

x = - \frac{11}{2} or x = \frac{9}{2}

\frac{1}{3} x = 12

2 x + 3 (5 x - 7) = 47

x^{2} - 14 x + 50 = 0

(2 - x)^{2} (x - \frac{9}{2}) < 0

\frac{7}{3}
