∣ 8 x ∣ + 4 = 10

x = - \frac{3}{4} or x = \frac{3}{4}

Solution steps

∣ 8 x ∣ + 4 = 10

Move

4

to the right side

∣ 8 x ∣ = 6

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

8 x = - 6 or 8 x = 6

8 x = - 6 or 8 x = 6

x = - \frac{3}{4} or x = \frac{3}{4}

\frac{8}{9}

0 = x^{2} - 6 x + 13

(1 + \frac{3 i}{n})^{2}

8 y^{3} - 2 y^{4}

- 4 (y - 6) \leq (- 9 + y) (- 2)
