-10|v+2|=-70

- 10 ∣ v + 2 ∣ = - 70

v = - 9 or v = 5

Solution steps

- 10 ∣ v + 2 ∣ = - 70

Divide both sides by

- 10

∣ v + 2 ∣ = 7

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

v + 2 = - 7 or v + 2 = 7

v + 2 = - 7 or v + 2 = 7

v = - 9 or v = 5

(20) (8) - (20 - 2 x) (8 - 2 x) = 40

(3 s - 2) - 9 > - 5

- 9.1 < d - 6.3

(\frac{1}{16})^{- 4}

(\frac{9}{17})^{6}
