-9+8|-4-k|=39

- 9 + 8 ∣ - 4 - k ∣ = 39

k = - 10 or k = 2

Solution steps

- 9 + 8 ∣ - 4 - k ∣ = 39

Move

9

to the right side

8 ∣ - 4 - k ∣ = 48

Divide both sides by

8

∣ - 4 - k ∣ = 6

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 4 - k = - 6 or - 4 - k = 6

- 4 - k = - 6 or - 4 - k = 6

k = - 10 or k = 2

2 x - 2 = 2 x - 31

- \frac{3}{4} - (- \frac{7}{6})

6 x - 7 x - 8 x - 4 = 10 + 20 - 50

∣ x ∣ + 13 < 27

5 x - 8 = 2 x + 7
