0=-2|r+100|

0 = - 2 ∣ r + 100 ∣

r = - 100

Solution steps

0 = - 2 ∣ r + 100 ∣

Switch sides

- 2 ∣ r + 100 ∣ = 0

Divide both sides by

- 2

∣ r + 100 ∣ = 0

Apply absolute rule: If

∣ u ∣ = 0

then

u = 0

r + 100 = 0

r + 100 = 0 : r = - 100

r = - 100

3 ∣ k - 3 ∣ + 1 = 9

3 - ∣ 2 m + 7 ∣ = 2

\frac{x}{3} - 5 = 1

∣ 30 - 4 x ∣ = 6 x
