2-10|K+1|=-78

2 - 10 ∣ K + 1 ∣ = - 78

K = - 9 or K = 7

Solution steps

2 - 10 ∣ K + 1 ∣ = - 78

Move

2

to the right side

- 10 ∣ K + 1 ∣ = - 80

Divide both sides by

- 10

∣ K + 1 ∣ = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

K + 1 = - 8 or K + 1 = 8

K + 1 = - 8 or K + 1 = 8

K = - 9 or K = 7

0 = ∣ k - 5 ∣

- 11 = ∣ 6 w - 5 ∣

∣ 2 x + 9 ∣ + 9 = 4 x^{4} x

∣ 10 - 5 m ∣ = 40

6 - 2 ∣ 4 x + 1 ∣ = - 56
