15 = ∣ 12 - 4 c ∣

c = - \frac{3}{4} or c = \frac{27}{4}

Decimal Notation

c = - 0.75, c = 6.75

Solution steps

15 = ∣ 12 - 4 c ∣

Switch sides

∣ 12 - 4 c ∣ = 15

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

12 - 4 c = - 15 or 12 - 4 c = 15

12 - 4 c = - 15 or 12 - 4 c = 15

c = - \frac{3}{4} or c = \frac{27}{4}

∣ - 4 c + 13 ∣ = 15

4 ∣ 2 y - 7 ∣ + 13 = 9

∣ 2 x - 3 ∣ + 5 = 10

\frac{a}{11} = 12

∣ 5 x ∣ = 5
