10-10|-8k+4|=10

10 - 10 ∣ - 8 k + 4 ∣ = 10

k = \frac{1}{2}

Decimal Notation

k = 0.5

Solution steps

10 - 10 ∣ - 8 k + 4 ∣ = 10

Subtract

10

from both sides

10 - 10 ∣ - 8 k + 4 ∣ - 10 = 10 - 10

Simplify

- 10 ∣ - 8 k + 4 ∣ = 0

Divide both sides by

- 10

∣ - 8 k + 4 ∣ = 0

Apply absolute rule: If

∣ u ∣ = 0

then

u = 0

- 8 k + 4 = 0

- 8 k + 4 = 0 : k = \frac{1}{2}

k = \frac{1}{2}

\frac{10 ( x + y ) ^{3}}{4 ( x + y ) ^{- 2}}

(7 y)^{2}

x^{\frac{3}{7}} \cdot x^{\frac{3}{14}}

- 3 + \frac{p}{7} = - 5
