3+5|8-2x|=63

3 + 5 ∣ 8 - 2 x ∣ = 63

x = - 2 or x = 10

Solution steps

3 + 5 ∣ 8 - 2 x ∣ = 63

Move

3

to the right side

5 ∣ 8 - 2 x ∣ = 60

Divide both sides by

5

∣ 8 - 2 x ∣ = 12

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

8 - 2 x = - 12 or 8 - 2 x = 12

8 - 2 x = - 12 or 8 - 2 x = 12

x = - 2 or x = 10

4 (x^{2} - 5) + 3 = 7

\frac{- 5}{3} x + \frac{2}{5} - \frac{1}{3} x + 1 = 0

(x + 9)^{2} (x + 6) > 0

8 = \frac{1}{4} (5 x - 8)

∣ 1 - 3 x ∣ > 2
