∣ 5 c - 6 ∣ = 31

c = - 5 or c = \frac{37}{5}

Solution steps

∣ 5 c - 6 ∣ = 31

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5 c - 6 = - 31 or 5 c - 6 = 31

5 c - 6 = - 31 or 5 c - 6 = 31

c = - 5 or c = \frac{37}{5}

∣ 5 x - 6 ∣ - 6 = x

∣ 5 x ∣ = 15

x^{2} - 2 x = 0

42 = ∣ 14 - 4 x ∣

∣ 3 x - 7 ∣ = 12
