-7|-n+3|-6=-90

- 7 ∣ - n + 3 ∣ - 6 = - 90

n = - 9 or n = 15

Solution steps

- 7 ∣ - n + 3 ∣ - 6 = - 90

Move

6

to the right side

- 7 ∣ - n + 3 ∣ = - 84

Divide both sides by

- 7

∣ - n + 3 ∣ = 12

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- n + 3 = - 12 or - n + 3 = 12

- n + 3 = - 12 or - n + 3 = 12

n = - 9 or n = 15

∣ 5 z + 6 ∣ - 19 = 0

0 = ∣ v - 5 ∣

∣ 2 x - 1 ∣ = 4 x - 3

∣ 5 - b ∣ = \frac{5}{2}

∣ 10 - 5 x ∣ - 7 = 18
