-4|c-7|-4=-8

- 4 ∣ c - 7 ∣ - 4 = - 8

c = 6 or c = 8

Solution steps

- 4 ∣ c - 7 ∣ - 4 = - 8

Move

4

to the right side

- 4 ∣ c - 7 ∣ = - 4

Divide both sides by

- 4

∣ c - 7 ∣ = 1

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

c - 7 = - 1 or c - 7 = 1

c - 7 = - 1 or c - 7 = 1

c = 6 or c = 8

2 \cdot (- 27)^{\frac{10}{3}}

\frac{s}{3} - 4 = 2

\frac{4 ^{5}}{4 ^{3}}

5 x^{3} - x^{2} + 15 x - 3

(- x + 2)^{2} (x - 1) (3 - x)^{4} (x + 5)^{3} \leq 0
