8=| c/(12)|

8 = \frac{c}{12}

c = - 96 or c = 96

Solution steps

8 = \frac{c}{12}

Switch sides

\frac{c}{12} = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{c}{12} = - 8 or \frac{c}{12} = 8

\frac{c}{12} = - 8 or \frac{c}{12} = 8

c = - 96 or c = 96

∣ 3 x + 14 ∣ = - 6 x

∣ x - 20 ∣ = 46

∣ x - 4 ∣ + 8 = 3 x

∣ 13 - 2 y ∣ = 19

1 + ∣ 7 + 3 x ∣ = 12
