|3c-3|+6=39

∣ 3 c - 3 ∣ + 6 = 39

c = - 10 or c = 12

Solution steps

∣ 3 c - 3 ∣ + 6 = 39

Move

6

to the right side

∣ 3 c - 3 ∣ = 33

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 c - 3 = - 33 or 3 c - 3 = 33

3 c - 3 = - 33 or 3 c - 3 = 33

c = - 10 or c = 12

∣ 16 x + 9 ∣ + 12 = 11

z - z^{2} = ∣ z ∣^{2} + 1

x^{3} + 2 x^{4} = - 1

∣ v ∣ - 14 = - 10

8 - 2 ∣ 5 x - 10 ∣ - 15 = 0
