2|2x-1|+5=15

2 ∣ 2 x - 1 ∣ + 5 = 15

x = - 2 or x = 3

Solution steps

2 ∣ 2 x - 1 ∣ + 5 = 15

Move

5

to the right side

2 ∣ 2 x - 1 ∣ = 10

Divide both sides by

2

∣ 2 x - 1 ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x - 1 = - 5 or 2 x - 1 = 5

2 x - 1 = - 5 or 2 x - 1 = 5

x = - 2 or x = 3

10 x^{2} - 23 x + 12

6 x^{2} + 4 x + 6 = 0

32 + 18 r + r^{2}

ln (\frac{1}{3})

- \frac{1}{6} (200)^{2} + 100 (200)
