1-3|-7x+7|=-104

1 - 3 ∣ - 7 x + 7 ∣ = - 104

x = - 4 or x = 6

Solution steps

1 - 3 ∣ - 7 x + 7 ∣ = - 104

Move

1

to the right side

- 3 ∣ - 7 x + 7 ∣ = - 105

Divide both sides by

- 3

∣ - 7 x + 7 ∣ = 35

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 7 x + 7 = - 35 or - 7 x + 7 = 35

- 7 x + 7 = - 35 or - 7 x + 7 = 35

x = - 4 or x = 6

∣ 4 - 2 y ∣ + 5 = 9

∣ 7 x + 3 ∣ = 2 x + 13

6 - ∣ 5 x - 10 ∣ = 4

∣ x - 6 ∣ = 4

∣ 8 y - 3 ∣ = 13
