58=|c-30|+8

58 = ∣ c - 30 ∣ + 8

c = - 20 or c = 80

Solution steps

58 = ∣ c - 30 ∣ + 8

Switch sides

∣ c - 30 ∣ + 8 = 58

Move

8

to the right side

∣ c - 30 ∣ = 50

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

c - 30 = - 50 or c - 30 = 50

c - 30 = - 50 or c - 30 = 50

c = - 20 or c = 80

∣ h ∣ = 3, y = 2

∣ - 4 k ∣ = - 88

∣ 3 x + 5 ∣ = 10

∣ z + 3 ∣ + 1 = 6

∣ 6 - 10 x ∣ = 14
