0=-9|s-5|

Solution

0 = - 9 ∣ s - 5 ∣

s = 5

Solution steps

0 = - 9 ∣ s - 5 ∣

Switch sides

- 9 ∣ s - 5 ∣ = 0

Divide both sides by

- 9

∣ s - 5 ∣ = 0

Apply absolute rule: If

∣ u ∣ = 0

then

u = 0

s - 5 = 0

s - 5 = 0 : s = 5

s = 5

x^{2} + 9 = x^{2} + 9

9 = 3 ∣ w ∣

0 = ∣ c + 185 ∣

∣ 2 x + 7 ∣ - 3 = 0

9 + ∣ x - 7 ∣ = 0
