13 = ∣ 2 b + 12 ∣

b = - \frac{25}{2} or b = \frac{1}{2}

Solution steps

13 = ∣ 2 b + 12 ∣

Switch sides

∣ 2 b + 12 ∣ = 13

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 b + 12 = - 13 or 2 b + 12 = 13

2 b + 12 = - 13 or 2 b + 12 = 13

b = - \frac{25}{2} or b = \frac{1}{2}

4 - 5 ∣ 10 + 5 x ∣ = - 51

∣ b + 3 ∣ = 3

∣ 3 x - 6 ∣ = 12

∣ 8 w + 5 ∣ = 21

25 - x^{2} = x^{2} - 25
