3 ∣ 3 x ∣ + 4 = 28

x = - \frac{8}{3} or x = \frac{8}{3}

Decimal Notation

x = - 2.66666 \dots, x = 2.66666 \dots

Solution steps

3 ∣ 3 x ∣ + 4 = 28

Move

4

to the right side

3 ∣ 3 x ∣ = 24

Divide both sides by

3

∣ 3 x ∣ = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 x = - 8 or 3 x = 8

3 x = - 8 or 3 x = 8

x = - \frac{8}{3} or x = \frac{8}{3}

4 a - 2 (a + 9) = 6

8 x + 6 x = 8 x + 4 x + 12

7 p^{2} = - 6 p + 3

\frac{2}{3} m + 14 = 0
