11=| x/7 |

11 = \frac{x}{7}

x = - 77 or x = 77

Solution steps

11 = \frac{x}{7}

Switch sides

\frac{x}{7} = 11

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{x}{7} = - 11 or \frac{x}{7} = 11

\frac{x}{7} = - 11 or \frac{x}{7} = 11

x = - 77 or x = 77

5 ∣ 2 x - 10 ∣ + 2 = 57

∣ 3 x - 2 ∣ = - 7

∣ r ∣ = 5

∣ 4 - 3 m ∣ = m + 10

∣ 5 x - 2 ∣ = 4 x - 4
