7=| c/7 |

7 = \frac{c}{7}

c = - 49 or c = 49

Solution steps

7 = \frac{c}{7}

Switch sides

\frac{c}{7} = 7

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{c}{7} = - 7 or \frac{c}{7} = 7

\frac{c}{7} = - 7 or \frac{c}{7} = 7

c = - 49 or c = 49

∣ y + 1 ∣ = 41

2 ∣ x - 12 ∣ + 5 = 3

∣ q ∣ = - 7

∣ 5 - 3 x ∣ = 7

∣ x + 1 ∣ = 7
