-15=9-4|c+10|

- 15 = 9 - 4 ∣ c + 10 ∣

c = - 16 or c = - 4

Solution steps

- 15 = 9 - 4 ∣ c + 10 ∣

Switch sides

9 - 4 ∣ c + 10 ∣ = - 15

Move

9

to the right side

- 4 ∣ c + 10 ∣ = - 24

Divide both sides by

- 4

∣ c + 10 ∣ = 6

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

c + 10 = - 6 or c + 10 = 6

c + 10 = - 6 or c + 10 = 6

c = - 16 or c = - 4

f (x) = ∣ x - 7 ∣ f (x) in d

- 4 ∣ 5 - x ∣ = - 12

18 = 3 ∣ 3 - 5 x ∣ - 3

∣ 6 + x ∣ + 6 = 3 x

7 ∣ x - 6 ∣ = 12
