z = - 6 or z = - 4

Solution steps

∣ - 2 z - 10 ∣ + 5 = 7

Move

5

to the right side

∣ - 2 z - 10 ∣ = 2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 2 z - 10 = - 2 or - 2 z - 10 = 2

- 2 z - 10 = - 2 or - 2 z - 10 = 2

z = - 6 or z = - 4

∣ 9 x ∣ - 6 = 57

- 2 ∣ j - 9 ∣ = - 6

∣ T A ∣ = 37.22 c m

a = ∣ 5 x + 3 ∣

∣ x - 3 ∣ - 10 = 2
