|v+8|-5=2

∣ v + 8 ∣ - 5 = 2

v = - 15 or v = - 1

Solution steps

∣ v + 8 ∣ - 5 = 2

Move

5

to the right side

∣ v + 8 ∣ = 7

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

v + 8 = - 7 or v + 8 = 7

v + 8 = - 7 or v + 8 = 7

v = - 15 or v = - 1

\frac{( 2 x ^{3} y ^{0} ) ^{4}}{x ^{9}}

8 x^{2} - 2 x = 3

10 - 2 (- 2)

\frac{3}{4} x - 7 = - 19

- 3 u + 2 = - 10 u + 30
