∣ 2 c - 13 ∣ = 66

c = - \frac{53}{2} or c = \frac{79}{2}

Solution steps

∣ 2 c - 13 ∣ = 66

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 c - 13 = - 66 or 2 c - 13 = 66

2 c - 13 = - 66 or 2 c - 13 = 66

c = - \frac{53}{2} or c = \frac{79}{2}

∣ - 9 b + 6 ∣ - 5 = 7

∣ 2 x + 8 ∣ + 50 = 2

∣ 2 x + 7 ∣ = 6 x + 13

∣ 7 x - 12 ∣ = 23

0 = ∣ 4 - x ∣
